Question

For one complete revolution of a particle in a circular path:
a) The distance and displacement are same.
b) The displacement is zero, but the distance is non zero.
c) The speed and velocity are same
d) The velocity remains constant throughout the motion.

Answer 1

option b) The displacement is zero, but the distance is non zero

because starting point = ending point so displacement = 0 and distance = circumference of circle = 2πr
