Question
A uniform electric field of 400 V/m exists in space as shown in graph. Two points A and B are also shown with their co-ordinates. The potential difference VB − VA in volts is :
Options
A.- 12 V
B.15 V
C.12 V
D.8 V
Solution
(C) dr = 
= 5 cm.
ᐃV =
dr cos θ= − E r cos θ.
= − [400 × 5 × 10-2 × cos (90o + 37o)]
= 12 V
= 5 cm.ᐃV =
dr cos θ= − E r cos θ. = − [400 × 5 × 10-2 × cos (90o + 37o)]
= 12 V
