Suppose a charge +q on Earth's surface and another +q charge is placed on the surface of the Moon. (b) Suppose the distance between the Moon and Earth is halved, would the charge q change?

Explanation

The distance between moon & earth is halved, the charge q=?
`(1)/(4piepsi_(0)).(q_(1)q_(2))/(((r)/(2))^(2))=G.(m_(E).m_(M))/(((r)/(2))^(2))`
There is no charge is charge q.
