Numerical problem from electrostatics

Share with:


A charge of 5 * 10-5c has been distributed between two spheres such that they repeal each other with a force 1N when their centers are 2m apart . Find the charge distribution
Asked Rahul

Answer
Let the total charge be q.
If the charge on one sphere is q1 then the charge on the other will be (q-q1)
Substitute in Coulomb’s law and get the value of q1 and q-q1
