Question -
If the electric flux entering and leaving an enclosed surface respectively is ϕ1\phi_1ϕ1​ and ϕ2\phi_2ϕ2​ the electric charge inside the surface will be
Options:
A .  Â (Ï•1+Ï•2)∈0\left(\phi_1+\phi_2\right)\in_0(Ï•1​+Ï•2​)∈0​ Â
B .  Â (Ï•1−ϕ2)∈0\left(\phi_1-\phi_2\right)\in_0(Ï•1​−ϕ2​)∈0​ Â
C .  Â (Ï•1+Ï•2)∈0\frac{\left(\phi_1+\phi_2\right)}{\in_0}∈0​(Ï•1​+Ï•2​)​ Â
D .  Â (Ï•1−ϕ2)∈0\frac{\left(\phi_1-\phi_2\right)}{\in_0}∈0​(Ï•1​−ϕ2​)​ Â
