Physics Question on Electric Field
Electric field at a distance ‘r’ from an infinitely long uniformly charged straight conductor, having linear charge density λ is E1. Another uniformly charged conductor having same linear charge density λ is bent into a semicircle of radius ‘r’. The electric field at its centre is E2 . Then
A
E2=rE1
B
E1 = E2
C
E1 = πrE2
D
E2 = πrE1
Answer
E1 = E2
Explanation
Solution
The correct answer is (B) : E1 = E2.
