Question

shell of Problem 1 A proton moves in a circular orbit of radius R at the speed of v outside a nonconducting s inner radius a and outer radius b. The spherical shell carries negative charge with a uniform density of p radius R 27 Problem 2.3 A long, straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire. The wire has a charge-per-meter of A, and the cylinder has a net charge-per-meter of 32. What are the charge- per-meter on the inner and outer surfaces of the cylinder? A) 0,3 -A, 5 B) D) 0,42 The electric field outside the cylinder a distance r from the axis is 1 of 4

Explanation / Answer

1] Here centripetal force is provided by electrostatic force.

So, mv^2/R = kq1*q2/R^2

R = kq*e/mv^2

=  k*e*rho*[4/3 pi b^3 - 4/3 pi a^3] /mv^2 because q = rho*volume

= 4pi*e*k*rho*[b^3 - a^3] /3mv^2

option a is correct.
