Question

A body of mass M and charge q is connected to spring of spring constant k. It is oscillating along x -direction about its equilibrium position, taken to be at x=0, with an amplitude A. An electric field E is applied along the x -direction. Which of the following statements is correct ?

Accepted Answer

(B) The total energy of the system is 1/2m ω ² A² + 1/2(q²E²)/k.

Answer

(A) The new equilibrium position is at a distance qE/2k from x=0.

Answer

(C) The total energy of the system is 1/2m ω ² A² - 1/2(q²E²)/k.

Answer

(D) The new equilibrium position is at a distance 2qE/k from x=0.
