A charged, non-conducting sphere, radius R, has a charge density p(r) = A/r¹, and a total charge Q = +5 C. Calculate the electric field as a function of radius, Ei(r), and sketch a plot of E(r) against r, over the range from 0 <r<5R. State the value and units of A. (8 marks) (d) Explain briefly what the electric field inside a conductor is, and why it has this value. (2 marks) O
