42. All electric charges are multiples of the charge on a(n) electron 45. It takes 3.3 J of energy to move a 1.2 C charge through part of an electric field. What is the potential difference between these two points? coulomb d. atom S neutron 43. How much work is done to transfer 1.20 C of charge through a potential difference of 48.0 V? 45. 46. A positive charge of 3.4 mC experiences a 7.7 x 10-8 N force when placed in an electric field. What is the strength of the electric field? 44. A 6.0-V battery does 1200 J of work transferring charge. How much charge is transferred? 47. As an electric field becomes stronger, the field lines should be drawn closer together thicker father apart thinner are used to store electrical energy
