A uniformly charged conducting sphere of 2.4 m diameter has a surface charge density of 80.0 μC/m2. What is the total electric flux leaving the surface of the sphere?

We know that charge on the sphere= Density x Area=80×10−6×4π(1.2)2=1.45×10−3CTherefore, the total electric flux leaving the surface of the sphere isϕ=qε0=1.45×10−38.86×10−12=1.6×108Nm2/C
