A square PQRS has a side of 2m. Charges of +20 C, -20 C and +20 C are placed at vertices P,R and S respectively. What will be the net force experienced by a 1 C charge placed at point Q ?

Explanation

To solve the problem, we will calculate the net force experienced by a 1 C charge placed at point Q in a square PQRS where charges are placed at vertices P, R, and S.

### Step 1: Identify the charges and their positions
- Charge at P (top left corner): \( +20 \, \text{C} \)
- Charge at R (bottom left corner): \( -20 \, \text{C} \)
- Charge at S (bottom right corner): \( +20 \, \text{C} \)
- Charge at Q (top right corner): \( +1 \, \text{C} \)
