Answer:
1003.9 Nm²/C
Step-by-step explanation:
Parameters given:
Radius of sphere, r = 1.88 m
Electric field at surface of sphere, E = 22.6 N/C
Electric Flux, Φ, is given as:
Φ = E * A
Where A = Surface area
Surface Area of sphere = 4 * pi * r²
= 4 * pi * 1.88²
= 44.4 m²
Φ = 22.6 * 44.4
Φ = 1003.9 Nm²/C
