Homework Statement
Three separate spheres next to each other. The one on the left is positive (charge of +25.5μ C). The one on the right is negative(-25.5μ C). The two are separated by 0.25m. The third sphere has a charge of +2.5μ C and is placed exactly halfway between the two. Find the force on the first, second, and third object(with direction, of course). (To clarify, the problem is asking for the total force on the first object (from the other two), etc.)
Homework Equations
Coulomb's law
The Attempt at a Solution
I successfully found the charge between the spheres on the left and right (completely disregarding the third one in the middle). That gave me 93.6 N.
That's about it because I can't seem to visualize the movement of all three objects. Help would be appreciated!
EDIT: I have the answers, just forgot to add them in here:
73.14 N is the force on the middle object (rightward)
The leftmost sphere: 56.92 N right
The rightmost sphere: 36.7 N right
