AIEEE 2003 | Electrostatics Question 277 | Physics

If the electric flux entering and leaving an enclosed surface respectively is $${\phi _1}$$ and $${\phi _2},$$ the electric charge inside the surface will be

$$\left( {{\phi _2} - {\phi _1}} \right){\varepsilon _0}$$

$$\left( {{\phi _2} + {\phi _1}} \right)/{\varepsilon _0}$$

$$\left( {{\phi _1} - {\phi _2}} \right)/{\varepsilon _0}$$

$$\left( {{\phi _1} + {\phi _2}} \right){\varepsilon _0}$$
