A particle of mass 2 kg is executing SHM and it s potential energy at extreme is 10 J . Velocity at mean position is 8 ~m / s . If potential energy at A / 2 (where A is amplitude) is U ₀ then find the value of 2 U ₀( in J) .
Correct answer
8
Step-by-step solution
1 2 k A^2=U_ -U_ = 1 2 m v_ ^2 U_ =2 J Potential energy at A 2 is =U_ + 1 2 k ( A 2 )^2=2+ 8 4 =4 J
