Plate Magnetic Power

What formula would you use for these situations?
Given the distance between two charged objects determine the electrostatic force.
Given the electric field strength due to two charges, determine the magnitude of the force on one of those charges.
Calculate the equivilant resistance for a series parallel or combination circuit.
Calculate the power for a series, parallel, or combination circuit.
Determine the current through a resistor in a series, parallel, or combination circuit.
Given the distance between two parallel plates the potential difference and the size of the charge, determine the kinetic energy of the charge.
Calculate the magnitude of the magnetic force on a current carrying wire.
1) Coulomb’s law
2) E = kQ/r^2
3) Rtotal = R1 + R2 + R3…
4) P = IV, Ohm’s law
5) P = IV
6) same
7) 1/2mv^2 = qV
F = IBlsin(theta), where theta is angle btwn B and I
