4. Given the Force and the electric field calculate the size of the charge in Coulombs.
25. You are given the size of the electric field, the distance and also the size of the charge. Since you're told you're moving one proton and you know the elementary charge on a single proton you know the charge. Since V=Ed and V=W/q you can set those two equations equal to each other to solve for the work required or you could solve for the electric potential difference and do it in two steps.
27. Given the Force and the electric field calculate the size of the charge in Coulombs.
29. You are given the Force, distance between the plates and the electric potential difference. Since V=Ed and E=F/q you can substitute the second equation into the first. Solve for the charge.
30. Given that capacitance and electric potential difference, solve for the charge.
