A particle executing S.H.M starts from the mean position. Its amplitude is ' A ' and time period ' T ' At what displacement its speed is one-fourth of the maximum speed?

Options

  1. AA 15
  2. BA 4
  3. C4 ~A 15
  4. DA 15 4

Correct answer

D. A 15 4

Step-by-step solution

aligned & V = A ^2- x ^2 & ~V _ = A & A ^2- x ^2 = A 4 & 16 ~A ^2-16 x ^2= A ^2 & 16 x ^2=15 ~A ^2 & x ^2= 15 16 ~A ^2 & x = A 15 4 aligned
