In a thundercloud there may be an electric charge of +40 c near the top of the cloud and -40 c near the bottom of the cloud. these charges are separated by about 2.0 km. what is the electric force between these two sets of charges? (ke = 8.99 ´ 109 n·m2/c2)

Electric force,

Explanation:

Given that,

Electric charge 1,

Electric charge 2,

Distance,

To find,

The electric force between these two sets of charges.

Solution,

There exists a force between two electric charges and this force is called electrostatic force. It is equal to the product of electric charged divided by square of distance between them.

k is the electrostatic constant

So, the electric force between these two sets of charges is .
