Four like charges each of +q are placed at the corners of a square of side a. The electric field intensity at the center of the square will be
Step 1: Given data
A square of side a has charge of at the corners.
Step 2: Analyzing the diagram
Step 3: Calculating electric field intensity at each corner
Step 4: Calculating electric field intensity at the center of the square
Hence, the electric field intensity at the center of the square will be
