A student stands on a bathroom scale in an elevator atrest on the 64th floor of a building. The scale reads 836 N.
a) As the elevator moves up, the scale reading increases to936 N, then decreases back to 836 N. Find the acceleration of the elevator.
b) As the elevator approaches the 74th floor, the scalereading drops to 742 N. What is the acceleration of theelevator?
c) Using your results from parts a andb, explain which change in velocity,starting orstopping, would take the longer time.
d) What changes would you expect in the scale readings on theride back down?
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
