Question

A cube with sides of area 22 cm2 contains a 21.2 nanoCoulomb charge. Find the flux of the electric field through the surface of the cube in unis of Nm2/C. Enter a number with one digit behind the decimal point.

Answer 1

Step-by-step explanation:

According to Gausses theorem, electric flux coming out of charge on all sides q is equal to

q / ε₀

q is charge , ε₀ is permittivity of air whose value is given by

8.85 x 10⁻¹²; q = 21.2 x 10⁻⁹ C

Putting the values we get

FLUX =
`(21.2*10^(-9))/(8.85*10^(-12))`

2.4 x 10³ Nm²/C
