A particle performs S.H.M. from the mean position. Its amplitude is 'A' and total energy is 'E'. At a perticular instant its kinetic energy is 3 E 4 . The displacement of the particle at that instant is

Options

  1. AA
  2. BA 8
  3. CA 4
  4. DA 2

Correct answer

D. A 2

Step-by-step solution

Total energy = E = 1 2 ~m ² ~A ² When kinetic energy is 3 E 4 , its potential energy is ( E - 3 E 4 )= E 4 Dividing Eq.(1) by Eq.(2), 4= A² x² x= A 2
