Electric Angle

Electricity and Magnetism Level 2

Note: the angles in the diagram are not drawn to scale.

An electric field line leaves a positive charge at an angle of \(60^{\circ}\) and enters a negative charge at an angle of \(\theta\). These angles are measured from the straight line joining the two charges.

The magnitude of the positive charge is 4 times the magnitude of the negative charge.

What is \(\theta?\)
