A particle moves with constant speed v along a circular path of radius r and completes the circle in time T . The acceleration of the particle is

Options

  1. A2 v T
  2. B2 r T
  3. C2 r^2 T
  4. D2 v^2 T

Correct answer

A. 2 v T

Step-by-step solution

Acceleration in circular motion aligned & a= v^2 r & But, aligned v & = 2 r T r & = v T 2 a & = v^2 v T / 2 & = 2 v T aligned aligned
