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 :

G1 Physics · Accepted Answer

The charge 5Q at x = 3a lies inside the sphere of radius 4a. The charge -2Q at x = -5a lies outside the sphere. By Gauss's law, Φ = Q(enclosed)/ε₀ = 5Q/ε₀
