A 6c charge is passing through a field with a strength of 450n/c calculate the electrostatic force acting on the charge

What is the rate of change in a objects position?

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
