Back to paper

Centripetal force "f" required for the circular motion of an object of mass "m" moving in a circle of radius "r" at a tangential velocity "v" is equal to ______.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. mv2 / r.

  • The magnitude of the centripetal acceleration is ac = v2/r 

  • Force = Mass × Accerlation = M(v2/r)
