Who knows this how to do this

YOU do !

The question GIVES you all of the numbers for both formulas. Except for the 'k' in the formula for the electric force. That's (9•10^9).

All you have to do is pluggum into where they go.

Plug the charges into the electrical formula, plug the masses into the gravity formula, and plug the distance into both uvum.

Then mash both formulas with your calculator, to get one simple final number for each one.

You'll discover why gravity is completely ignored while working inside atoms.
