Graphical variation of electric field due to a uniformly charged insulating solid sphere of radius R, with distance r from the center O is represented by:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The electric field inside a solid insulated sphere is given by
for r < R where p is volume charge density. Hence, the electric field varies linearly with the distance as
Now, the electric field for r > R is given by w
Thus, the graph starts decreasing as a power law graph as shown in the figure for the region r > R. Hence, this graph is the right option.
