Homework Statement
Two small charged objects of the same mass and volume are brought into brief contact with each other. If the initial charges on the two objects are -3.00 x10^-6 and -1.50 x10^-6, what is the electric force between the objects when they are separated to a distance of 0.500m after contact?
The answer is 1.82 x10^1 N
Homework Equations
F=KQ1Q2/r^2
The Attempt at a Solution
I thought it is just plug in the numbers but i get a different answer. So is there anything that goes on when they are in contact?
F= (9.0x10^9)(-3.00x10^-6)(-1.50x10^-6)/(0.500)^2
=0.162N
