If the radius of a sphere is 1/(4π)m and the electric flux density is 16π units, the total flux is given by,(a) 2(b) 3(c) 4(d) 5The question was posed to me in unit test.The question is from Electric Field Density in portion Electrostatic Fields of Electromagnetic Theory

Answer»

Correct CHOICE is (c) 4

Explanation: Total flux leaving the ENTIRE surface is, ψ = 4πr^2D from GAUSS law. Ψ = 4π(1/16π^2) X 16π = 4.
