A wheel is rolling on a plane surface. The speed of a particle on the highest point of the rim is 8 ~m / s . The speed of the particle on the rim of the wheel at the same level as the centre of wheel, will be :

Options

  1. A4 2 ~m / s
  2. B8 ~m / s
  3. C4 ~m / s
  4. D8 2 ~m / s

Correct answer

A. 4 2 ~m / s

Step-by-step solution

If V_B=2 V Point A is instantaneous center of rotation Given V_B=8 ~m / s aligned & V =4 ~m / s & ~V _ p = 2 v ~V _ p =4 2 ~m / s & correct (1) aligned
