Question

Charge is uniformly distributed in a space. The net flux passing through the surface of an imaginary cube of side a in the space is f. The net flux passing through the surface of an imaginary sphere of radius a in the space will be

• A. f
• B. $\frac{3}{4\pi}$f
• C. $\frac{2\pi}{3}$f
• D. $\frac{4\pi}{3}$f

Answer 1

Answer: (D)

$\frac{4\pi}{3}$f

Answer 2

=

f₂ = r × $\frac { 4 \pi \mathrm { a } ^ { 3 } } { 3 \in _ { 0 } }$

f₂ = f × $\frac { 4 } { 3 }$p
