A spring-block system undergoes vertical oscillation
above a large horizontal metal sheet with uniform
positive charge. The time period of the oscillation
is T. If the block is given a charge Q, its time
period of oscillation will be
(A) T
(B) > T
(C) < T
(D) > T if Q is positive and < T if Q is negative

A particle of mass m, initially at rest, is acted
upon by a variable force F for a brief interval of
time T. It begins to move with a velocity 'u' after
the force stops acting. F is shown in the graph as
a function of time. The curve is a semicircle,
then A capacitor of capacitance C is charged to a
potential difference V from a cell and then
disconnected from it. A charge + Q is now given
to its positive plate. The potential difference across
the capacitor is now
