Question

a sphere of radius 3cm has a charge 8.85nC kept at its center find the electric flux through the sphere ( class 12 )​

Answer 1

Answer:

10^6 Nm²C-¹ [a^n means aⁿ]

Explanation:

Since the sphere is a closed structure and symmetric about its centre.

Therefore, the sphere is a symmetrical closed surface. It means we can use applying Gauss theorem here.

Gauss theorem:

In a closed surface, symmetrical about the charge(s), electric flux is the ratio of magnitude of charge and permittivity of the medium. Flux = q/ε

Hence,

Flux through sphere = q/ε

Flux = (8.85 μ) / (8.85 x 10^(-12))

Flux = 8.85 x 10^(-6) / (8.85 x 10^(-12))

Flux = 1/10^(-6)

Flux = 10^6 Nm²C-¹
