1. The problem statement, all variables and given/known data
an alpha particle (charge=+2.0e) is sent at high speed toward a gold nuclues Charge= +79e. What is the electrical force acting on the alpha particle when it is 2.0 times 10^ -14m away from the gold nucleus


2. Relevant equations



3. The attempt at a solution

its 91 N but i need the steps of how i got the answer
