Question

An electric field of 20 N/C exists along the x-axis in space. Calculate the potential difference V_B - V_A where the points A and B are given by, 

(a) A = ( 0, 0 ); B - ( 4 m, 2m) 

(b) A - ( 4 m, 2m);B=(6m, 5m) 

(c) A - ( 0, 0 ); B - ( 6 m, 5 m ). 

Do you find any relation between the answers of parts (a), fa) and (c) ?

Answer 1

(a) A = (0, 0) B = (4, 2)
