. What is the change in electric potential energy of two particles on with a charge of 1.2 nC and the other with 2.3 nC that start with a distance of 0.05 m between them and thn are separated by 1.1m?

Suppose a wire with a current is pushed upward by a magnetic field. how would the wire move if the direction of the current reversed? explain your answer.

Select the three ways that the parallel-plate capacitor differs from a car battery.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
