Question -
Answer -
(a) Dielectric constant of the mica sheet, k =6
Initial capacitance, C =1.771 × 10−11 F

Supply voltage, V = 100 V

Potential across the plates remains 100 V.
(b) Dielectric constant, k = 6
Initial capacitance, C =1.771 × 10−11 F

If supply voltage is removed, then there will be noeffect on the amount of charge in the plates.
Charge = 1.771 × 10−9 C
Potential across the plates is given by,
