Question

The number of electric field of lines emerged out from 1 C charge is _________(ε₀ = 8.85 x 10⁻¹² MKS)(A) 9 x 10⁹
(B) 8.85 x 10²
(C) 1.13 x 10¹¹
(D) infinite

Answer 1

Electric field lines are imaginary force lines that are not truly available, but the effects of these lines are real.

It is helpful to know that evaluating the electric field of different charged particles is complex to solve with coulombs law.

The value of ε₀ is given above.  

N = q/€

N = 1/8.85 × 10^-12

N = 1.13 × 10^11.

Answer 2

Holla ^_^

☸ Required Answer is C) 1.13 x 10¹¹
