Question

If work done is taking 4 C charge from a point A whose potential is -10C to another point B. The work
done is 100 J, then electric potential of point B is..​

Answer 1

Answer:

given,

work done in moving a 4 C charge =100J

electric potential at A=-10 joule /coulomb

electric potential at point B=?

then, work done in moving a charge from one point to another is given by

W(AB)=q(V(B)-V(A)

V(B)-V(A)=W/q

V(B)-V(A)=100/4=25

V(B)=25+V(A)

=25-10=15

V(B)=15 Joule/ coulomb
