# Find the electrical force between them.?

Two pellets, each with a charge of 0.80 microcoulomb (8.0×10−7C ), are located 3.4cm (3.4×10−2m ) apart.

I could really use help solving this and an explination of how to solve it thank you.

Update:

I understand to use coulombs law but I dont understand how to use it what to plug in where.

F= k q_1 * q_2 / r^2

Use Coulomb's law

Coulomb's law is that the magnitude of the force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of the charges and inversely proportional to the square of the distance between them

If they have the same sign the force is repulsive if they are different then it's attractive.

F= 1/4pi epsilon _ not * 8.0E-7 * 8.0 E-7 / (3.4 E -2)^2
