Question

The flux passing through the surface $S_5$ will be

• A. $-0.135N{m}^2{C}^{-1}$
• B. $-0.054N{m}^2{C}^{-1}$
• C. $-0.081N{m}^2{C}^{-1}$
• D. $-0.054N{m}^2{C}^{-1}$

Answer 1

The correct option is A $-0.135N{m}^2{C}^{-1}$

${\varphi }_5=-5l^3=-5\times 27\times {10}^{-9}$
$=-135\times {10}^{-}3=-0.135N{m}^2{C}^{-1}$
