Along non-conducting hollow cylinder with inner radius, ri and outer radius, r2 is charged with a uniform positive charge with a charge density ? . (a) use gauss's law in differential form for regions outside the cylinder (r > r2) to show that the electric field decreases as 1/r (note that no marks will be awarded for using gauss's law in integral form).

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
