Question

If the electric flux entering and leaving an enclosed surface respectively is φ1 and φ2, the electric charge inside the surface will be:-

Answer 1

Answer : (a) (ϕ2−ϕ1)∈0(ϕ2−ϕ1)∈0

Explanation : Net flux through surface = ϕ2−ϕ1ϕ2−ϕ1

Using gauss's law

ϕ2−ϕ1=qenc∈0ϕ2−ϕ1=qenc∈0

qenc=(ϕ2−ϕ1)∈0.
