# A charge $(q_1)$ is placed at the origin (O). Another charge $(q_2)$ is placed at point P 10 cm away from the origin, towards its right. On the line joining the two charges, the net electric potential is zero at point Q (which is 6 cm away from the origin), as shown in the given figure.What is the potential at point O due to the charge placed at point P?

$(A) 1.2 \times 10^4 V$
