MHT CET Physics question
A linear harmonic oscillator of force constant N/m and amplitude 0.01 m has a total mechanical energy of 160 J. Which of the following statements are correct? A) maximum P.E. is 100 J B) maximum KE is 100 J C) maximum P.E. is 160 J D) minimum P.E. is zero
Answer: (D)
Solution
Maximum KE J, so B is true; since the total energy is 160 J, the potential energy varies between 60 J
