Q. Four charges are placed at the circumference of the dial of a clock as shown in figure. If the clock has only hour hand, then the resultant force on a positive charge $q_{0}$ placed at the centre, points in the direction which shows the time as $x : 30$ . The value of $x$ is:

$F_{n e t}$ is between $7&8$

$∴ 7 : 30$
