What is Gauss law for electric flux?
What is Gauss law for electric flux? Gauss’s law states that: The net outward normal electric flux through any closed surface is proportional to the total electric charge enclosed within that closed surface. How do you fix electric flux problems? Solution: To compute electric flux, we need the magnitude of the electric field, area of […]

How do you calculate perihelion?
How do you calculate perihelion? The perihelion distance P=a(1−e) and the aphelion distance A=a(1+e) where e=0.875 is the eccentricity. This gives a perihelion distance of 2.375AU and an aphelion distance of 35.625AU. How is Pericenter calculated? The angle from the ascending node to the pericenter, measured in the plane of the orbit….The eccentricity of an […]
