Net flux emitted from a spherical surface of radius a according to Gauss's theorem is given by φ_net = q_in / ε₀. Find the total flux emitted when q_in = 0.
- φ_net = 0
- φ_net = q_in / ε₀
- φ_net = q_enclosed / ε₀
- φ_net = q_in / 4πε₀
Correct answer: φ_net = 0
Solution
According to Gauss's theorem, the net flux through a closed surface depends on the charge enclosed within the surface. If the enclosed charge (q_in) is zero, the net flux (φ_net) is also zero.
