Determine the charge on each set of particles. 1.6 x 1019 protons = C
Spheres A, B, and C have charges +8 C, +12 C, and -5 C, respectively. Spheres A and B touched each other and then separated. Sphere A then touched sphere C and then separated
a. What is the total charge on the three spheres before and after touching each other?
b. What is the final charge on each sphere assuming they are identical?
c. What is the final charge on each sphere assuming that rA = rB = 2rC?
Electric Field:
You are helping to design a new electron microscope to investigate the
structure of the HIV virus. A new device to posit
ion the electron beam consists of a charged
circle of conductor. This circle is divided into two half circles separated by a thin insulator
so that half of the circle can be charged positively and half can be charged negatively. The
electron beam will go
through the center of the circle. To complete the design your job is to
calculate the electric field in the center of the circle as a function of the amount of positive
charge on the half circle, the amount of negative charge on the half circle, and the
radius of
the circle.
