Answer #1

The net force on q2 will be resultant of force due to q1 and force due to q3. The force due to q1 will be towards right side and force due to q3 will be towards left.

The force due to q1 = 9X10^9X1x1x10^-12/1^2 = 9X10^-3 N

The force due to q3 = 9x10^9X1x2x10^-12/9 =2X10^-3 N

SO, the force due to q1 is more, so net force will be directed towards right.
