Question

Can u guys answer question 5

Answer 1

Answer:

Necessarily not. It maybe zero or maybe not.

Explanation:

We can understand it in two cases:

Case-1

The body does not move from its position and stays in rest. In this case, the displacement and distance, both will be zero.

Case-2

The body is moving on a circular track. Here, after one complete revolution, the body reaches the same position where it started. Hence its displacement is zero. But its distance is the circumference, which is 2πr.

Hence displacement is zero, whereas distance is non-zero.

Hence distance may or may not be zero.
