    A spring-block system undergoes simple harmonic motion on a smooth horizontal surface. The block is now given some positive charge, and a uniform horizontal electric field to the right is switched on. As a result,

    A)  The time period of oscillation will increase

    B)  The time period of oscillation will decrease

    C)  the time period of oscillation will remain unaffected

    D)  the mean position of simple harmonic motion will shift to the left

    Correct Answer: C

    Solution :

    The time period will depend upon the restoring force only. The restoring force will be again the spring force only, so time period will not be changed. However, the equilibrium position will be shifted in the direction of the applied force.
