Witch of the following is not an appropriate unit for power

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.

The strong nuclear force acts over a small distance than the electrostatic force. true or false
