Two coaxial conducting cylindrical shells have equal and opposite charges. the inner shell has charge +q and an outer radius a, and the outer shell has charge -q and an inner radius b. the length of each cylindrical shell is l, and l is very long compared with b. find the potential difference va − vb between the shells. (use any variable or symbol stated above along with the following as necessary: k for the coulomb's constant.)

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
