Q. A metal foil of negligible thickness is introduced between two plates of a capacitor at the centre. The capacitance of capacitor will be :

(a) same      (b) double

(c) half        (d) K times

Q. A solid sphere and a hollow sphere of equal diameters are raised to the smae potential. Then,

(a)  hollow sphere has more charge.     
(b) both have equal charge.
(c)  only hollow sphere has charge.     
(d) solid sphere has more charge.

Q. Two capacitors of capacitances C1 and C2 are connected in parallel. If a charge q is given to the assembly, the charge gets shared. The ratio of the charge on the capacitor C1 to the charge that on C2 is :

(a)  C1/C2            (b)  C2/C1

(c)  C1C2             (d) 1/C1C2

Q. A stationary charge produces :

(b) a magnetic field only.          
(c) both electric and magnetic fields.       
(d) an electromagnetic wave.

Q. Electric field varies as r-3 due to :

(a) a point charge.        
(b) an infinite line charge.    
(c) an electric dipole     
(d) an infinite plane sheet of charge.
