Chapter 1, Problem 25EAP
The star Betelgeuse s about 600 light-years away. If it explodes tonight, (a) we’ll know because it will be brighter than the full Moon in the sky. (b) we’ll know because debris from the explosion will rain down on us from space. (c) we won’t know about it until about 600 years from now.

Your answer is partially correct.
Two small objects, A and B, are fixed in place and separated by 2.98 cm in a vacuum. Object A has a charge of
+0.776 μC, and object B has a charge of -0.776 μC. How many electrons must be removed from A and put
onto B to make the electrostatic force that acts on each object an attractive force whose magnitude is 12.4 N?

Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = rad,
the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is = 2 rad/sec².
What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector
in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle
by observing a right triangle. (20 pts)
