Question

Uniform electric field of magnitude 100 V/m in space is directed along the the y=3+x.find the potential difference between the point A (3,1)and (1,3)

Answer 1

E = 100 V / m 

y = 3 + x 

Potential difference (V) 

E = -dV /dr 

dV = -Edr 

dV = -100 ( 1 - 3) - 100 ( 3 -1) 

dV = -100 + 300 -300 + 100 

dV = 0 V 

Answer 2

Answer:

0 V

Explanation:

Potential difference between A and B is  

V  BA = −Edx−Edy= −100(1−3)−100(3−1)=200−200=0V
