A test charge of +2x10^-6 C is placed halfway between a charge of 5.5x10^-6 C and another of 2.5x10^-6 separated by 0.1m. What is the magnitude of the force on the test charge in N?

if v is in meters per second, B in teslas, and L in meters, then the units of the right-hand side of the equation are joules per coulomb or volts (the correct SI units for E ).

A test charge of +1 µC is placed halfway between a charge of +3.8 µC and another of +9.6 µC separated by 10 cm. What is the magnitude of the force (in N) on the test charge?

The electric power P drawn from a generator by a lightbulb of resistance R is P = V2/R, where V is the line voltage. The resistance of bulb B is 87% greater than the resistance of bulb A. What is the ratio PB/PA of the power drawn by bulb B to the power drawn by bulb A if the line voltages are the same?
