A large non-conducting surface is there with surface charge density `5 muC//m^2`. How much force will it apply on a point charge of `2 muC` when placed at a distance of 2cm from the surface ?

Explanation

To solve the problem step by step, we need to calculate the force exerted by a large non-conducting surface with a given surface charge density on a point charge placed at a certain distance from the surface.

### Step 1: Identify the given values
- Surface charge density, \( \sigma = 5 \, \mu C/m^2 = 5 \times 10^{-6} \, C/m^2 \)
- Point charge, \( Q = 2 \, \mu C = 2 \times 10^{-6} \, C \)
- Distance from the surface, \( d = 2 \, cm = 0.02 \, m \)

### Step 2: Calculate the electric field due to the infinite surface
