Explanation:
Given:
- The magnitude of three identical charges,
- Length of the edge of the square a=3 cm
- Magnitude of fourth charge ,Q=3 nC
According to coulombs Law the force F between any two charge particles is given by
where r is the radial distance between them.
Since the force acting on the charge particle will be in different directions so according to triangle law of vector addition
