Question 16 POST_UTME_UI • 2021 • PHYSICS • objective

A particle of mass $m$ is moving in a circular path of radius $R$ with a cons\tant speed $v$. If the particle is subjected to a centripetal force $F_c = \frac{mv^2}{R}$, what is the work done by this force as the particle moves through an angle $\theta$?

Answer Options

Correct Answer A. \( W = \frac{1}{2}mv^2\( 1 - \cos \theta \ \) )
B. \( W = \frac{1}{2}mv^2\( 1 + \cos \theta \ \) )
C. \( W = mv^2\( 1 - \cos \theta \ \) )
D. \( W = mv^2\( 1 + \cos \theta \ \) )
Correct Answer
A
Correct Option:
\( W = \frac{1}{2}mv^2\( 1 - \cos \theta \ \) )
