A vehicle of mass 200 kg is moving along a levelled curved road of radius 70 m with angular velocity of 0 . 2 rad s - 1 . The centripetal force acting on the vehicle is:

Options

  1. A560   N
  2. B2800   N
  3. C2240   N
  4. D14   N

Correct answer

A. 560   N

Step-by-step solution

The centripetal force is given by F = M v 2 R = M R ω 2 The given data is M = 200   kg R = 70   m ω = 0 . 2   rad   s - 1 The magnitude of the force is F = 200 × 70 × 0 . 2 2   N ⇒ F = 560   N
