Question

A particle is performing a uniform circular motion along the
circumference of a circle of radius 'R' and 'T' is the periodic time. In
the time 'T/4' its displacement and distance covered are respectively​

Answer 1

Explanation:

Displacement is equal to the distance between initial and final position. so in this case displacement will be equal to 2r, the diameter of the circle.

&

Distance is equal to the length of actual path traversed by the object. so in this case, displacement will be equal to the half of the circumference i.e. πr.
