A
1 V
B
2 V
C
3 V
D
4 V
Explanation: 

Detailed explanation-1: -If a parallel plate capacitor of plate area 2m2 and plate separation 1m store the charge of 1.77*10-11 C. What is the voltage across the capacitor? On substituting values of d, A, we get C=2€0. V=1 V.

Detailed explanation-2: -Final Answer: 1130 km2. Q. What is the area of the plates of a 2 F parallel plate capacitor, given that the separation between the plates is 0.5 cm? [You will realisefrom your answer why ordinary capacitors are in the range of F orless.

Detailed explanation-3: -The area of a parallel plate capacitor is 1 ‘m^2‘ and the separation between its two plates is ‘10^(-4)m‘ . The intermediate space is filled with a material of dielectric constant 7. A certain amount of charge raises its potential to 300 V.

Detailed explanation-4: -For parallel plate capacitors, the capacitance (dependent on its geometry) is given by the formula C=⋅Ad C = ⋅ A d, where C is the value of the capacitance, A is the area of each plate, d is the distance between the plates, and is the permittivity of the material between the plates of the parallel capacitor.

Detailed explanation-5: -so area of plate, A=Cd=8. 85×103×(5×10)=1. 694×109m2.
