Avan de graaf generator has a motor that runs its 57 cm long (full length around) rubber belt at a speed of 103 cm/s. when the motor has run for 19 s, the safety pole bends like a spring of stiffness 2.2 n/m, pulling its ball-like tip inward to a distance of 44 cm from the center of the tip of the safety pole to the center of the 23 cm diameter globe. they have an unbent distance of 52 cm.
(1) what is the charge on the small ball at t = 19 s? 1.947 correct: your answer is correct. μc
(2) what is the magnitude of the electric field that pulls the small ball toward the large one? 90.39548023 correct: your answer is correct. kn/c
(3) what is the magnitude of the electric field half way between the two balls? 722.4818182 correct: your answer is correct. kn/c
(4) what is the surface charge density of the sphere? 11.71548863 correct: your answer is correct. μc/m2
(5) what is the linear charge density on the charged part of the belt?
(6) what is the total charge on the belt at any given time? nc
