A body attached to one end of a string performs motion along a vertical circle. Its centripetal acceleration, when the string is horizontal, will be [ g = acceleration due to gravity]

Options

  1. Azero
  2. B5g
  3. C3g
  4. Dg

Correct answer

C. 3g

Step-by-step solution

When string is horizontal its speed is given by aligned & V = 3 gr & Centripetal acceleration = V ^2 r =3 ~g aligned
