I think it's true
I'm not really sure
Answer:
The total electric flux through the shell = 34804 N.m²/C
Explanation:
φ = E.A ........................... Equation 1
Where φ = total electric flux through the shell, E = Electric Field, A = surface Area of the sphere
But,
A = 4πr² ................................... Equation 2
Where r = radius of the sphere.
Given: r = 1.4 m,
constant: π = 3.143
Substituting these values into equation 2,
A = 3.143(1.4)²
A = 6.16 m²
Also Given: E = 5650 N/C,
Substituting into equation 1,
φ = 5650(6.16)
φ = 34804 N.m²/C
Thus the total electric flux through the shell = 34804 N.m²/C
Answer:
If conditions are just right, you can see Polaris from just south of the equator. Although Polaris is also known as the North Star, it doesn't lie precisely above Earth's North Pole. If it did, Polaris would have a declination of exactly 90 degree.
