Chapter 17, Problem 2P
* You rub two 2.0-g balloons with a wool sweater. The balloons hand from 0.50-m-long very light strings. When you attach the strings together at the top, the balloons hang away from each other each string making an angle of 37° with the vertical. (a) Represent the situation with the force diagram for each balloon and determine the magnitudes of the forces on the diagram. (b) What can you say about the magnitudes of the forces that the balloons exert on each other? Explain. (c) Will the ratio of the forces that the balloons exert on each other change if the charge on one balloon is two times larger than on the other? How do you know?

QUESTION 5
Problem
A new type of force was discovered by physicists with the following expression:
a
Fnew
+ Bex + 3x4
where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higgs Boson (a type of
particle) and a black hole.
Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do
to achieve this feat? (For simplicity, consider that no energy is lost in the process)
Solution
determine the work done we apply the following
W =
dx
Evaluating the above, we get
W =

for the limits from x¡ to xf
substituting x1 and x2 as the limits, the work done is expressed as
W =
