Question
In the diagram below, each division on the horizontal axis is 0.20 m while each division on the vertical axis is 1.5 V. What is the electric field in each of the regions specified below?
(a) from 0.0 m to 0.30 m
V/m
(b) from 0.30 m to 0.50 m
V/m
(c) from 0.50 m to 0.80 m
V/m
Explanation / Answer
Here ,
electric field is given as
E = -change in electric potenital / distance
A)
for x = 0.0 m to 0.30 m
as change in potetnial = zero
ELectric field = ZERO
B)
for 0.30 to 0.50 m
E = -(3 - 4.5)/(0.5 - 0.3)
E = 7.5 V/m
the electric field is 7.5 V/m
C)
NOw, for 0.50 m to 0.80 m
change in potential = zero
electric field = Zero
