Question

Two charges −q each are placed at the vertices A and B of an equilateral triangle ABC. If M is the mid-point of AB, the net electric field at C will point along ______.

Options

• CA

• CB

• MC

• CM

Answer 1

Two charges −q each are placed at the vertices A and B of an equilateral triangle ABC. If M is the mid-point of AB, the net electric field at C will point along CM.

Explanation:

The net electric field at point C will be directed vertically upward, along the line perpendicular to AB, towards the midpoint of AB (point M), specifically along line CM.
