If linear charge density of a wire as shown in the figure is λ, then
A
electric field at the center is 
B
electric field at the center of the loop is 
C
electric field at the centre of the loop is 
D
None of the above
Text Solution
Verified by ExpertsThe correct answer is:
D
Electric field at center due to circular portion is zero because electric field due to each charged element at center will be cancel out by the electric field due the charged element of its just opposite side.
