A positive test charge q is released from rest at distance r away from a charge of +Q and a distance 2r away from a charge of +2Q. 1)How will the test charge move immediately after being released?

Complete Question

The complete question is shown on the first uploaded image

The correct option is the second option

Explanation:

 Generally the electric force exerted by the charge Q  on the  charge  (q) is mathematically represented as

 Generally the electric force exerted by the charge 2Q  on the  charge  (q) is mathematically represented as

Now the net force exerted on q is

Looking at the resulting equation we see that

This implies that the charge q would move to the right
