## Homework Statement

Two charged pellets are pulled apart to twice their original separation. (a) Which is likely to be larger, the gravitational force or the electrical force between them? Why? (b) Which will change by a greater factor when they are pulled apart, the gravitational force or the electrical force between them? Why?

## Homework Equations

F

_{g}= (G x m

_{1}x m

_{2}) / r

^{2}

F

_{e}= (K x q

_{1}x q

_{2}) / r

^{2}

## The Attempt at a Solution

a) Well, assuming 6.673 × 10

^{−11 }for the constant of G and 8.987 x 10

^{9}for the constant of K, I would assume that the electrical force would be higher.

b) I am assuming that they would change at the same factor when they are pulled apart.

Am I assuming correct or am I wrong?
