Homework Statement
A metal sphere of radius a is surrounded by a metal shell of inner radius b and outer radius R, as shown in the diagram below. The flux through a spherical Gaussian surface located between a and b is 1.20Q/εo and the flux through a spherical Gaussian surface just outside R is 0.80Q/εo.
a) What is the total charge on the inner sphere? (Express your answer as a multiple of Q. For example, if the total charge is 0.2Q, then input 0.2).
Homework Equations
flux=E4pi*r^2=Qenclosed/epsilon not
The Attempt at a Solution
I understand that I need to use the ratios of 1.2Q/Enot=Qenclosed/Enot and .8Q/Enot=Qenclosed/Enot
I'm just not sure what to do with these two things
