Concept

Problem: Two protons are 2.0 fm apart.A. What is the magnitude of the electric force on one proton due to the other proton?B. What is the magnitude of the gravitational force on one proton due to the other proton?C. What is the ratio of the electric force to the gravitational force?

FREE Expert Solution

The electric force is expressed as:

Fe=kq1q2r2, where k is Coulomb's constant and is the distance between two charges q1 and q2.

The gravitational force that one object exerts on another is:

Fg=Gm1m2r2, where G is gravitational constant, m1 is the mass of the first object, mis the mass of the second object, and is the distance between the objects.
