Question

A charge +5 microcoloub is at distance 5 cm from a surface of a square. Find the electric flux passing the square in the presence the cube.

Answer 1

flux is simply given by

Φ=Qin/ε

Qin=5*10⁻⁶C

ε=8.85*10⁻¹²

Φ=5*10⁻⁶/8.85*10⁻¹²

=0.56*10⁶

(i forgot the unit of flux and epislon so plz forgive me)
