Question

Choose the correct option.

Two-point charges of A = +5.0 μC and B = -5.0 μC are separated by 5.0 cm. A point charge C = 1.0 μC is placed at 3.0 cm away from the centre on the perpendicular bisector of the line joining the two point charges. The charge at C will experience a force directed towards

Options

• point A

• point B

• a direction parallel to line AB

• a direction along the perpendicular bisector

Answer 1

a direction parallel to line AB

Explanation: 

The situation resembles a point along the equatorial line of a dipole. Therefore, force-directed would be along a direction parallel to line AB.
