A particle is performing U.C.M. along the circumference of circle of diameter 50 ~cm with frequency 2 ~Hz . The acceleration of the particle in m / s ^2 is

Options

  1. A2 ^2
  2. B4 ^2
  3. C8 ^2
  4. D^2

Correct answer

B. 4 ^2

Step-by-step solution

aligned & d =50 ~cm & r =25 10⁻² ~m , f =2 ~Hz & a = r ^2=4 ^2 f ^2 r =4 ^2 4 25 10⁻²=4 ^2 aligned
