15. A conductor has a surface charge density of 300nC/m^2. If the area of the conductor is 15m^2 what is the electric flux through the given area of the conductor (60= 8.85 x 10^-12C^2Nm?).
(a) 5.08 x10Nm²/C
(b) 2.08 x 10Nm2/C
(c) 1.08 x10
Nm²/C
(d) 0.08 x 10Nm2/C

E = sigma/2 * epselon naught

E = 300 * 10^-9/(2 * 8.854 * 10^-12)

E = 1.7 * 10^4 N/C

Assuming that the electric field is uniform all across the surface:

Then, Electric flux = E * A

Electrix flux = 1.7 * 10^4 * 15 = 2.5 x 10^5 Nm^2/C

It should be b)

the answer is 46 mls because when you add the speed per second it increses the speed

i think its c if i'm wrong
