Question

6. Two charges, both of +2.00 uC are located 30.0 cm above and below the origin on the y axis. A third charge of + 4.00 HC is located +40.0 cm from the origin. Find the magnitude and direction of the net force acting on the particle on the x axis.

Answer 1

Ans. We use Coulomb's law to get the net force on the third charge.

The charges on the y axis are equal and they are equidistant from the third charge. Hence the y -components of the net force on the third charge cancel out.The direction of the net force on the third particle is along + x(the charge is repelled).
