Two conducting spheres of radii R 1 and R 2 respectively are charged and joined by a wire. The ratio of electric fields of spheres is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
When two spheres are joined charge flows till it equalises. Hence electric potential is same.
V 1 = V 2
⇒ 
..........(i)
Ratio of electric fields N 
⇒ 
........(ii)
or 
[From Eq. (i)]
