Question

A simple pendulum is oscillating with amplitue A and angular frequency `omega` At ratio of kinetic energy to potential energy is
A. `(x^(2))/(A^(2)-x^(2))`
B. `(x^(2)-A^(2))/(x^(2))`
C. `(A^(2)-x^(2))/(x^(2))`
D. `(A-x)/(x)`

Answer 1

Correct Answer - C
`(KE)/(PE)=((1)/(2)momega^(2)[A^(2)-x^(2)])/((1)/(2)momega^(2)x^(2))=(A^(2)-x^(2))/(x^(2))`
