(A) A dielectric slab of thickness t, is introduced between the plates of parallel plate capacitor of area A and separation d (where t less than d). Find an expression for the capacitance with the dielectric slab.

(B) A copper sphere of capacitor C is dropped in ocean. Will the capacitance of the sphere increase, decrease or remain same? Justify.

(C) A capacitor is connected across a source of potential difference V and then the separation 'd' between the plates is increased using insulating stick. Plot 'V' vs 'd' graph for the given capacitor.
