Suppose that N electrons enter the second Stern-Gerlach device shown in figure Q7.8. Let the angle 8 be such that
cos 0 = 3/5 and sin0 = 4/5.
(a) How many electrons come out of the channel of the third device? (Justify your response using the Rules.)
(b) Now suppose that we block the electrons that come out of the channel of the second device before they go into the y-
shaped funnel. How many come out of the channel of the third device now?
Answer
(a) 0
(b) 144N/625.

A block of mass m = 1.34 kg (Block 1) at rest at Point A on an arc of smooth circular surface of radius L = 30 m. Another block of mass M = 3.22 kg (Block 2) is at the bottom of the arc as shown in Fig.6. The line between the center of the arc and Point A and the line between the center of the arc and Point B make an angle 0 = 35 deg. If Block 1 is released and slides on the arc and hits Block 2, Block 1 stops at Point B and Block 2 starts to move along the arc. What is the velocity of Block B right after the collision in m/s. Keep three significant figures for the answer. g= 9.80 m/s. There is no friction.
