Question on: JAMB Physics - 1993

Here's how to solve this problem:

1. Recall the formula for capacitance: The capacitance (C) of a parallel plate capacitor is given by:

   C = ε₀ * A / d

   where:

   • ε₀ is the permittivity of free space (8.85 x 10⁻¹² F/m, but the question provided 9 x 10⁻¹² which will be used for simplicity.)
   • A is the area of the plates.
   • d is the distance between the plates.

2. Rearrange the formula to solve for distance (d):

   d = ε₀ * A / C

3. Convert the given values to standard units:

   • A =
