Question

Two positive charges $q_{2} a n d q_{3}$ are placed along the y-axis as shown. They exert a net force on $q_{1}$ in the positive x- direction. If a third positive charge Q is placed on the x-axis at (X, 0) then the net force on $q_{1}$

Shall increase in the positive x- direction

Solution

The correct option is A Shall increase in the positive x- direction
$q_{1}$ should have negative charge as the net force is along positive direction due to charges $q_{2} a n d q_{3}$ . Hence the net force due to Q will support the force due to $q_{2} a n d q_{3}$ .
