Question

When placed 1.18 m apart, the force each exerts on the other is 11.2 N and is repulsive. What is the charge on each

Answer 1

`q=41.62\ \mu C`

Step-by-step explanation:

Given that,

Force between two objects, F = 11.2 N

Distance between objects, d = 1.18 m

We need to find the charge on each objects. The force between charges is as follows :

`F=(kq^2)/(r^2)\\\\q=\sqrt{(Fr^2)/(k)} \\\\q=\sqrt{(11.2* (1.18)^2)/(9* 10^9)} \\\\q=41.62\ \mu C`

So, the charge on each sphere is
`41.62\ \mu C`.
