Final answer:
The electric field for r
Step-by-step explanation:
The electric field for rr < rr1 can be calculated using the expression: E = k*q1 / (rr^2), where k is the electrostatic constant and q1 is the charge. For rr1 < rr < rr2, the electric field can be calculated using the same expression as above, but with q1 replaced by the net charge enclosed by the Gaussian surface.
