Two solid stainless steel, conducting spherical balls, of radii r1 = 2.0 cm and r2 = 10.0 cm, are connected by a thin copper wire, as shown in the figure (click on link below for figure). The spheres are 1.00 m apart, center-to-center. A total charge of Q = 12 microC is shared by the two spheres.
Link for figure: http://img108.imageshack.us/img108/5205/physicszs5.jpg
a) What are the charges Q1 and Q2 carried by the ball #1 (on the left) and ball #2 (on the right), respectively?
b) Taking the potential at infinity to be zero, what is the electric potential at the surfaces of the two spheres?
c) What are the electric fields just inside the spheres?
d) What are the electric field magnitudes just outside the spherical surfaces, and in what directions do they point?
e) What are the electric field x- and y- components, and also magnitude and direction, at a point P, 1.00 m away from the wire along the y-axis, as shown in the figure?
This is the review for my test. Please help. Thanks
