Find the potential at point A and B.

0 votes

Two point charges q1=+2.25 nC and q2= -6.55 nC  are 0.100 m apart. Point B is 8.00x10^-2 m from q1 and 6.00x10^-2 m from q2.Take the electric potential to be zero at infinity.

figure---> 

A) Find the potential at point A.

B)Find the potential at point B.

C)Find the work done by the electric field on a charge of 2.5 nC that travels from point B to  A point A.
