Avery long cylindrical dielectric rod of radius r spins slowly about its axis. a uniform magnetic field bo is applied along this axis. the dielectric has an electric susceptibilityx (a) find the displacement field d(r). (b) using d 6,e p. express e in terms of p (c) find the electromotive field (let's call this force per unit charge fo(r)) acting on charges in the dielectric resulting form the lorentz force (d) the electromotive field you found induces a polarization in the dielectric. find the polar- ization. note: this is not simply p(r) є0ke(r) (griffiths 4.30) because in addition to feel the push/pull from electric fields (from free charges [if any] and polarization) there is the electromotive field acting on the dielectric. (e) find the bound volume and surface charges corresponding to the polarization p(r) (f) the rotating polarization charge distribution sets up a current distribution which in turn sets up a magnetic field that will act on moving charges. argue that we are justified in neglecting this (possible) contribution

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
