A proton is located a small distance above the earths

Question

Solve the all parts of given problem:

Problem: A proton is located a small distance above the earth's surface and is released above a second proton, which exerts an electrostatic force on the released proton. The electrostatic force exerted on the released proton is large enough that it cancels out the gravitational force exerted on it by the earth.

Part A: Find the distance between the two protons?

Part B: Find the Electrostatic force between the two protons?

Part C: Find the electrostatic force exerted on the released proton due to the second proton?

Part D: Find the gravitational force exerted on the released proton due to the earth?

Part E: Find the gravitational force exerted on the released proton due to the second proton?

Part F: How would the electrostatic force compare if instead an electron were released instead of a proton?

I need help to find the electrostatic force exerted on the released proton due to the second proton.
