When a condenser of capacitor C is givenn a charge Q, the P.D. across its plates is V. the diemnsional formula for QV is

A dielectric of constant K is slipped between the plates of parallel plate condenser in half of the space as shown in the figure. If the capacity of air condenser is C, then new capacitance between A and B will be (c )/(2) (B) (c )/(2K) (C) (C)/(2) [1+ K] (D) (2[1+ K])/(c )

Two condensers of capacity C and 2C are connected in parallel and these are charged upto V volt. If the battery is removed and dielectric medium of constant K is put between the plates of first condenser, then the potential at each condenser is.
