C = 10 μF d = 8 cm
C ' = ? d ' = 4 cm
C ' = ? d ' = 4 cm
If d is halved then C will be doubled.
Hence, C ' = 2C = 2 × 10μF = 20μF

The capacity of a parallel plate condenser is 10μF when the distanc...
Given Data:
- Initial capacitance (C1) = 10 µF
- Initial distance between plates (d1) = 8 cm
- Final distance between plates (d2) = 4 cm
Formula:
- The capacitance of a parallel plate capacitor is given by the formula:
C = (ε₀ * A) / d
where,
C = capacitance
ε₀ = permittivity of free space (8.85 x 10^-12 F/m)
A = area of the plates
d = distance between the plates
Calculations:
- Initial capacitance (C1) = (ε₀ * A) / d1
- Final capacitance (C2) = (ε₀ * A) / d2
- From the above equations, we can write:
C2 = C1 * (d1 / d2)
- Substituting the given values:
C2 = 10 µF * (8 cm / 4 cm)
C2 = 10 µF * 2
C2 = 20 µF
Therefore, the capacity of the parallel plate condenser will be 20 µF when the distance between its plates is reduced to 4 cm. Hence, the correct answer is option 'C' - 20 µF.
- Initial capacitance (C1) = 10 µF
- Initial distance between plates (d1) = 8 cm
- Final distance between plates (d2) = 4 cm

- Substituting the given values:
C2 = 10 µF * (8 cm / 4 cm)
C2 = 10 µF * 2
C2 = 20 µF
Therefore, the capacity of the parallel plate condenser will be 20 µF when the distance between its plates is reduced to 4 cm. Hence, the correct answer is option 'C' - 20 µF.

Capacitor (C) = Aۥ/d
capacitor is inversely proportional to distance
If distance is reduced then capacitor will be increased
Thus if 10uf then capacitor will be increased 20uf .
