Can resultant of three vectors be zero?
The resultant of the two vectors lie in the same plane. Hence, three vectors in single plane cannot give the resultant zero. For the resultant of three vectors to be zero, resultant of two should be equal and opposite to the third.
When can two vectors be added to zero?
Solution: When the two vectors are equal and opposite in direction, then its sum will be equal to zero.
Can a vector have a zero magnitude?
Answer: Magnitude cannot be negative. It is the length of the vector which does not have a direction (positive or negative). … The zero vector (vector where all values are 0) has a magnitude of 0, but all other vectors have a positive magnitude.

Can a resultant force be negative?
About Resultant Forces
A resultant force can be calculated by taking forces that act along the same line and add them together. If the forces are in the same direction as each other, then they have a positive value. If one force is acting in the opposite direction to another one of the forces is given a negative value.
What happens when a vector is negative?
vectors. … except that multiplying by a negative number will reverse the direction of the vector’s arrow. For example, multiplying a vector by 1/2 will result in a vector half as long in the same direction, while multiplying a vector by −2 will result in a vector twice as long but pointed…
Does zero vector have direction?
With no length, the zero vector is not pointing in any particular direction, so it has an undefined direction. We denote the zero vector with a boldface 0, or if we can’t do boldface, with an arrow →0.
Can you add two unequal vectors?
No it is not possible to obtain zero by adding two vectors of unequal magnitudes. Sum of two vectors can only be zero if they are equal in magnitude and opposite in direction.
Can we add two vectors of different dimensions?
Two vectors of the same size (i.e. number of elements) can be added: this adds the corresponding elements to create a new vector of the same size. You can’t add two vectors of different sizes.
Can you add two vectors representing physical quantities having different?
Answer : Two vectors representing physical quantities having different dimensions cannot be added nor subtracted, in order to add them they should be of dimension.
Can you have AxB AB?
Answer: If A=/=0 and B=/=0 then AxB cannot be equal to A.B because cross product is a vector quantity having a magnitude equal to ABsinθ and direction perpendicular to the plane containing A and B while the dot product A.B is a scalar quantity having its value equal to ABcosθ.
Is it possible to add three vectors?
Yes, it is possible to add three vectors of equal magnitudes and get zero. and A , → B → and C → ,given these three vectors make an angle of with each other.
Can a vector have zero component along a line and still have non zero magnitude?
Yes, a vector can have zero components along a line and still have a nonzero magnitude. Example: Consider a two dimensional vector 2 i ^ + 0 j ^ . This vector has zero components along a line lying along the Y-axis and a nonzero component along the X-axis. The magnitude of the vector is also nonzero.
Can you combine two equal vectors to give a zero resultant prove your answer?
it is not possible to get zero resultant by combinig two vector having different magnitude.it is only possible if we combine two vectors of same magnitude in opposite direction.
Can two vectors of different magnitude be combined to give zero resultant can three vectors do explain?
No, two vectors of different magnitudes can not give zero resultant. Three vectors can give zero resultant but two vectors can not. This is because the effect of vectors cancels out only when they act in the opposite direction and have the same magnitude.
Can the sum of two vectors be a scalar?
Answer. No, it is impossible for the magnitude of the sum to be equal to the sum of the magnitudes.
Can a vector be zero if one of its components is not zero?
A vector with zero magnitude cannot have non-zero components . Because magnitude of given vector ˉV=√V2x+V2y must be zero . This is possible only when V2x and V2y are zero.

Are two vectors orthogonal?
We say that 2 vectors are orthogonal if they are perpendicular to each other. i.e. the dot product of the two vectors is zero.
What is a zero vector explain the need of a zero vector?
Answer:- It is defined as a vector that has zero length or no length and with no length, it is not pointing to any particular direction. Therefore, it has no specified direction or we can say an undefined direction.
How do you know if a vector is positive or negative?
If the x-component of a vector points in the negative x-direction, it has a negative value. If the x-component of a vector points in the positive x-direction, it has a positive value. The sum of the x-components of all the vectors is the x-component of the resultant vector.
What is an opposite vector?
The vector −a is the opposite of the vector a. The vector −a has the same magnitude as a but points in the opposite direction.
What is the difference between vector a negative and vector A?
So, the difference between a negative of a vector and a difference vector is that a difference vector is the sum of a negative of a vector and another vector.
Can sum of three non coplanar vectors give zero resultant?
No, three non-coplanar vectors cannot ad up to given zero resultant because for non-coplanar vectors the resultant of the two vectors will not lie in the plane of third vector , and so the resultant cannot cancel the third vector to given null vector .
