Question

8. A point charge Q is kept at the centre of a cube of side 10cm. What will be the electric flux i) through the cube? ii) through one face of the cube?​

Answer 1

Answer:

The square can be considered as one face of a cube of edge 10 cm with a centre where charge q is placed. According to Gauss's theorem for a cube, total electric flux is through all its six faces. Therefore, electric flux through the square is 1.88 × 105 N m2 C−1.

Answer 2

Explanation:

The square can be considered as one face of a cube of edge 10 cm with a centre where charge q is placed. According to Gauss's theorem for a cube, total electric flux is through all its six faces. Therefore, electric flux through the square is 1.88 × 105 N m2 C−1.
