A +50µC charge moves along a straight line a distance of 20 cm in a uniform electric field of 120 N/C. The proton is traveling at an angle of 30 degrees relative to the direction of the electric field. How much electrical energy (in Joules) did the charge gain or lose? And is it a gain or loss?
When is it easier to calculate the energy in eV and then convert to Joules if necessary? When is it easier to calculate the energy in Joules first and then convert to eV if necessary?
