Electric Forces: A Fun and Shocking Discovery!

What is the arrangement of charges in the figure mentioned?

The figure has a symmetrical arrangement with qa = qb = +7.85 uC, and qc = qd = -7.85 uC, with q being positive.

What is the direction of the force on charge q?

Using the symmetry of the arrangement, determine the direction of the force on charge q.

Arrangement of Charges

The figure in consideration features a symmetrical setup where charges qa and qb are both +7.85 uC, while charges qc and qd are both -7.85 uC.

Direction of Force on Charge q

The force on charge q is away from charges qa and qb. As a result, the net force on charge q will be in the direction away from charges qa and qb.

Exploring Electric Forces in a Symmetrical Arrangement

Electric forces can provide surprising revelations, especially in symmetrical configurations like the one described. When charges qa and qb are of equal magnitude and positive, they exert forces on charge q that push it away from them. Conversely, charges qc and qd, with equal magnitudes but opposite signs, create forces on q that cancel each other out.

This intriguing interaction results in the net force on charge q pointing away from charges qa and qb. The symmetry of the arrangement plays a crucial role in determining the direction of the force and helps unveil the fascinating world of electric forces.
