A particle of mass 5 kg is moving on a circle of radius 1m with an angular velocity of 2 rads ⁻¹ . The centripetal force is

Options

  1. A10 N
  2. B40 N
  3. C30 N
  4. D20 N

Correct answer

D. 20 N

Step-by-step solution

Given, mass, m = 5kg, radius, r = 1m Angular velocity, =2 rad s ⁻¹ Centripetal force = Mass * Centripetal acceleration aligned & =m ^2 r & =5 (2)^2 1 & =20 ~N aligned
