Four point charges , , and are located at the corners of a square ABCD of side 10cm. What is the force on a charge of placed at the centre of the square?
The symmetry of the figure clearly indicates that 1 µC charge will experience equal and opposite forces due to equal charges of 2 µC placed at A and C. Similarly, 1 µC charge will experience equal and opposite forces due to –5 µC charge placed at D and B.
