Acylindrical shell of surface charge density o and radius r is coaxial with the z axis. find the force per unit length (length along the z-direction) on the right half of the cylinder, where the right half is defined to be -r/2 < < ¢ < +t/2. do this two ways: (a) use the maxwell stress tensor (à la griffiths example 8.2) (b) use the force per unit area on a shell of charge, griffiths equation (2.51): 1 2 f = 2€0 1 2 1 в, в; 1 e, e tij 7dy в? )

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
