Question

A sphere of radius 1m encloses a charge of 5μC. Another charge of 5μC is placed inside the sphere. The net electric flux would be :


  1. four times
  2. double
  3. three times
  4. zero

A
three times
B
double
C
zero
D
four times
Solution
Verified by Toppr

We know flux ϕ=Qenclosedϵ0
as Qenclosed by sphere=+5μc5μc =0
ϕ=0
