Question

A body of mass m is moving with a constant speed v on a circular path of radius r. The centripetal force acting on the body is

• A.
  $mvr$
• B.
  $\frac{mv}{r^2}$
• C.
  $\frac{m{v}^2}{r}$
• D.
  $mg$

Answer 1

The correct option is C

$\frac{m{v}^2}{r}$
Mass of the body = m
Speed of the body = v



Radius of the circular path = r
Centripetal force, $F=\frac{m{v}^2}{r}$

Hence, the correct answer is option (c).
