What is the electric force between a glass ball with 3.5 µC of charge and a rubber ball with -5.0 µC of charge when they are separated by 5 cm?
The Attempt at a Solution
This seems like a simple plug in problem but I'm having a little trouble.
First i get the elementary charges of both the glass and rubber balls
so 1.6E-19*3.5=5.6E-19 for q(1)
and 1.6E-19*5=8E-19 for q(2)
So i plug in the numbers i know and get:
I plug this into the program my school uses for physics homework and it tells me I am wrong.
Can you see where I am doing something wrong? please any help is appreciated.
