A) \[2.5\ volt/m\]
B) \[-2.5\ volt/m\]
C) \[2/5\ volt/m\]
D) \[-2/5\ volt/m\]
Correct Answer: A
Solution :
Intensity at 5m is same as at any point between B and C because the slope of BC is same throughout (i.e., electric field between B and C is uniform). Therefore electric field at R = 5m is equal to the slope of line BC hence by \[E=\frac{-dV}{dr}\]; \[E=-\frac{(0-5)}{6-4}=2.5\frac{V}{m}\] At R = 1 m, \[E=-\frac{(5-0)}{(2-0)}=-2.5\frac{V}{m}\] and at R = 3m potential is constant so E = 0.You need to login to perform this action.
