φ=1000=(q/ε0) q=8.854 × 10-12 × 1000 q=8.854 × 10-9 C

Q. If the number of electric lines of force emerging out of a closed surface is $1000$ , then the charge enclosed by the surface is

$8.854 \times 1 0^{- 9} C$

$8.854 \times 1 0^{- 4} C$

$8.854 \times 1 0^{- 1} C$

$8.854 C$

$ϕ = 1000 = \frac{q}{ε _{0}}$
$q = 8.854 \times 1 0^{- 12} \times 1000$
$q = 8.854 \times 1 0^{- 9} C$

Q. If the number of electric lines of force emerging out of a closed surface is 1000 , then the charge enclosed by the surface is

8.854×10−9C

8.854×10−4C

8.854×10−1C

8.854C
