(10%) Problem 10: A spherical capacitor consists of a single conducting sphere of radius R-18 cm that carries a positive charge Q- 35 nC. The capacitance for this spherical capacitor is given by the equation C4A. 14% Part (a) Write an equation for the energy stored in a spherical capacitor when a charge Q is placed on the capacitor. Write your equation in terms of R, Q, and ?0. -? 14% Part (b) Use Gauss's Law to write an equation for the electric field everywhere inside the spherical capacitor (r R that is concentric with the spherical capacitor. Write an equation 14% Part (f) Find the total energy stored in the field by integrating the energy over the radius outside the conducting shell. Write this total 14% Part(g) Calculate the energy stored in the capacitor in units of microjoules. for the total energy contained in the shell in terms of Q, r, dr, and eo. energy contained in the shell in terms of Q, R, and eo. Grade Summary Deductions U= 0%Explanation / Answer
Here to find the energy stored we have to use the formula
U = ( Q^2)/( 8*pi*?0*R)
Where
Q= Charge, R = Radius
Q = 3.5*10^-8 C , R = 0.18 m
U = (3.5*10^-8)^2 / (8*3.14*8.85*10^-12*0.18)
U = 3.06*10^-5 J or 3060000 micro joule
