Question

vo identical small metal spheres are both given positive charges one of +0 and the of +3QTh n below. When they reach equilibrium, one sphere is at the bottom of the tube, at nd the other is at height y. e two spheres are then dropped into a vertical non-conductive tube as (10 pts.) +30 +0 The two spheres are pushed into contact with one another and then released as shown in the figure below. When they again reach equilibrium, one sphere is at the bottom of the tube and other is at height y2 spheres pushed in contact with one another spheres repel and settle at arn equilibrium position What is the expression y2 in terms of yi? Hint: When two spheres touch one another, assume the charges redistribute evenly on each. 212 e. None of the above 13 Tun noint chargcs au and are 0.50 m apart on the x-axis. Charge qi has a value of

Explanation / Answer

after touching , charge on each sphere = (3Q + Q)/2 = 2Q

k (3Q) (Q)/y21= k (2Q) (2Q)/y22

y22 = 4y21/3

y2 = 2 y1/sqrt(3)
