JEE Main 2024 Physics question
Two charges of 5Q and –2Q are situated at the points (3a, 0) and (–5a, 0) respectively. The electric flux through a sphere of radius '4a' having center at origin is-
Answer: (D)
Solution
Only the charge 5Q (at distance 3a < 4a) lies inside the sphere; −2Q (at 5a) is outside. By Gauss's law, φ = /ε₀ = 5Q/ε₀.
