A variable parallel plate capacitor and an electroscope are connected in parallel to a battery. The reading of the
\( \mathrm{P} \) electroscope would be decreased by :
(i) Increasing the area of overlap of the plates
W
(ii) Placing a block of paraffin wax between the plates
(iii) Decreasing the distance between the plates
(iv) Decreasing the battery voltage
(A) Only (i), (ii) and (iii) are correct
(B) Only (i) and (ii) are correct
(C) Only (ii) and (iv) are correct
(D) Only (iv) is correct
