A correct electrical-mechanical analogy sees the electric energy in a capacitor

Question

A correct electrical-mechanical analogy sees the electric energy in a capacitor and the magnetic energy in an inductor that is connected to the capacitor by means of a wire as respectively analog to O the gravitational energy of a falling ball and the kinetic energy of that falling ball. O the positive energy of the Yang and the negative energy of the Yin. O the elastic energy of a spring and the kinetic energy of a ball attached to the spring O the gravitational energy of a lifted box and the work done by the applied force on it. the kinetic energy of a sliding puck and the work done by friction with the ground

Explanation / Answer

Here,

for the energy in inductor and energy in capacitor

as these are periodic sinusoidal functions

these are analogous to the fuctions of energy is simple harmonic motion of spring

hence , the correct option is 3)

the elastic potential energy of a spring and the kinetic energy of a ball attached to the spring
