1)What is the force between two equal charges (1 Coulomb) that are separated by a distance of 1 km? 2)Suppose that the charge of one of the charges in problem #1 is reduced to half of its original value. How does the new force compare to the original force?

Expert Solution

1)

Force between two charges is calculated by Coulomb's Law.

Here, is force between two charges and separated by distance and is Coulomb's constant.

Substitute 1 C for & , 1000 m for and for in above equation of force.

N

2)

Let value of charge of be reduced to half and it becomes .

Here, is force between two charges and separated by distance .

Substitute 1 C for , 0.5 C for , 1000 m for and for in above equation of force.

N

Thus, when the charge of one of the charges is reduced to half of its original value, force will also be reduced to half.
