Answer 1

given

charge q = 42*10^-9 C

distance d = 0.165 m

electric field E = 300 N/C

a) from the relation

electric force F = qE

F = 42*10^-9*300 = 1.26*10^-5 N

direction: in the direction of electric field that is towards right

b) work w = F*d = 1.26*10^-5*0.165 = 2.079*10^-6 J

c) from the relation work = change in electric potential energy = 2.079*10^-6 J

d) potential difference = work/charge = 2.079*10^-6/42*10^-9 = 49.5 V
