Question

Which of the following represents a zero vector?

A) Position vector at the origin B) Displacement vector of a stationary particle

C) Acceleration vector of a particle moving in a straight line with uniform velocity in the same

direction D) Force vector with a magnitude of three units​

Answer 1

C) Acceleration vector of a particle moving in a straight line with uniform velocity in the same

If the velocity is uniform, then it means that object isn't accelerating. i.e acceleration=0.

So, the magnitude of acceleration is zero making the vector a zero vector.
