Four point charges q1 =2μC, q2 =−5μC, q3 =2μC, and q4 =−5μC are located at the corners of a square ABCD of side 10 cm respectively. What is the force (in N) on a charge of 1μC placed at the centre of the square? |
Unity Zero -1 None of these |
Zero |
All the forces cancel out each other. Hence, the net force is zero. |
