Four charges + 8Q – 3 Q + 5 Q and – 10 Q are kept inside a closed surface. What will be the outgoing flux through the surface,

According to Gauss’s Law, the total electric flux (Φ) through a closed surface is given by:
Φ = Qenclosed/ε0
​where Qₑ is the total charge enclosed within the surface.
The total charge enclosed is:
Q enclosed = (+8Q) + (-3Q) + (+5Q) + (-10Q)
Q enclosed = 8Q – 3Q + 5Q – 10Q = 0
​Since the total enclosed charge is zero, the outgoing flux is also zero.
Thus, the correct answer is (b) 0 V·m.
