Question

A 641-C point charge is at the center of a cube with sides of length 0.47 m. What is the electric flux through one of the six faces of the cube? (Give your answer in scientific notation using N.m2/C as unit)

Answer 1

Answer:

12 × 10^12 Nm^2/C

Explanation:

According to the Gauss's theorem

The total electric flux by the enclosed charge is given by

Charge enclosed / €0

So flux by each surface

= Q enclosed / 6 × €0

= 641 / ( 6 × 8.854 × 10^-12)

= 12 × 10^12 Nm^2/C
