Can someone please help with the following questions? I've attached the pictures below. I appreciate it! For the problem that asks about the meaning of of p0, I already have the answer for that, I just need help with part b.
Transcribed Image Text:Consider a very long cylinder of radius R and length L, carrying a charge Q which is uniformly distributed throughout the whole
volume of the cylinder.
(a) Determine the magnitude of the electric field E(r) outside the cylinder, at a distance r > R from the axis of the cylinder.
Your answer should only include the variables R, L, Q,r, and constants such as TT and ɛp.
(b) Determine the magnitude of the electric field E(r) inside the cylinder, at a distance r <R from the axis of the cylinder.
Your answer should only include the variables R, L, Q, r, and constants such as t and ɛo.
![A solid sphere of radius R has a charge density given by p(r) = Po r/R. Here r is the distance from the center of the sphere,
and po is a constant with units C/m3.
(a) What is the physical meaning of po ?
[ ]It's the charge density at the center of the sphere, i.e. at r = 0.
[ ]It's the charge density on the surface of the sphere, i.e. at r = R.
[ ]It's the average charge density of the sphere.
[ ]The constant po has no physical meaning at all, it's just some constant.
