At each corner of a square of side l there are point charges of magnitude Q, 2Q, 3Q, and 4Q. What is the magnitude and direction of the force on the charge of 2Q?

magnitude of force on charge 2Q  =

Direction of force on charge = 61 ⁰

Explanation:

The magnitude on the force on the charge can be evaluated by finding the net force acting on the charge 2Q  i.e x-component of the net force and the y-component of the net force

║F║ =  =  after considering the forces coming from Q, 3Q and 4Q AND APPLYING COULOMBS LAW

magnitude of force acting on 2Q =

The direction of the force on charge 2Q is calculated as

tan ∅ = = 1.8284

therefore ∅ =  1.8284

= 61⁰
