Answer:
Capacitance C 
where εo is permitivity of free space, A is area of plates of condenser and x is separation distance between plates.
K is constant that equals to εoA.
if we differentiate eqn.(1), 
Hence rate of change of capacitance is directly proportional to velocity of movement of plates and
inversly proportional to square of separation distance d at that instant
