Questions
A linear harmonic oscillator of forte constant 2x106 N/m and amplitude of 0 . 01 m has a total mechanical energy of 160 J. Its
detailed solution
Correct option is B
Elastic potential energy, =12kx2=12×2×106×(0⋅01)2=100J TLe enerry is converted into kinetic onergy . . Maximum K.E. = 100 I Given that total mechanical energy is 16O j Hence maximum potential enerry is 160 j So, b and c are correct.Talk to our academic expert!
