Question 11 POST_UTME_PAN-ATLANTIC_UNIVERSITY • 2020 • PHYSICS • objective

A particle of mass ( m ) is moving in a circular path of radius ( r ) with a cons\tant speed ( v ). The particle is subject to a centripetal force \( F_c \) given by \( F_c = \frac{mv^2}{r} \). If the particle's speed is doubled, what is the new centripetal force required to keep the particle in its circular path?

Answer Options

A. \( \frac{mv^2}{r} \)
B. \( \frac{2mv^2}{r} \)
Correct Answer C. \( \frac{4mv^2}{r} \)
D. \( \frac{8mv^2}{r} \)
Correct Answer
C
Correct Option:
\( \frac{4mv^2}{r} \)
