Question

A particle is moving in a circle of diameter 5m. Calculate the distance and displacement of the particle after 3.5 revolutions.​

Answer 1

Explanation:

If a particle is moving with constant speed on a circular path then it is said to have uniform circular motion.

Distance covered in two rounds is,

s=2×2πr

=4×3.14×7.5

=94.2m

Total displacement after two rounds will be zero because particle comes at the same initial point.
