Question

can a moving body have zero relative velocity with respect to another body give one
example

Answer 1

when the object travels in circular path

Answer 2

Yes, the zero relative velocity is possible.

Let us understand with an example.

For example: If you are traveling in a car which is moving at a velocity of 60 m/s with respect to ground. Your velocity will also be 60 m/s with respect to ground, but your relative velocity with respect to car is zero because you are part of the same car. Hence, the relative velocity can be zero.
