A spherically symmetric charge distribution produces the electric field E = (5700r^2) N/C, where r is in m
a) what is the electric field strength at r = 25.0 cm?
b) What is the electric flux through a 34.0-cm diameter spherical surface that is concentric with the charge distribution?
c) How much charge is inside this 34.0-cm diameter spherical surface?
