Question

A particle is moving in a circle of radius $4cm$ with constant speed of $1cm/s$. Find the time period of the particle.

Answer 1

Time Period T is defined as time required by particle to complete one revolution of a circle.
Distance traveled by particle in one revolution $=2\pi r$
$=2\times 3.14\times 4$
$=25.132cm$
Speed of particle $=1cm/s$
Time period, T = $\frac{Distance}{Speed}$
= $\frac{25.132}{1}$

= $25.132s$
