Question
![4. A point mass m with positive charge q is
suspended from the ceiling by a thread.
Nearby, a charged object causes the point
charge q to deflect from the vertical. Our task
will be to find the angle of deflection in
various cases. (Refer to Table at right.)
c) Finally, suppose that the nearby object is a
long positively charged line, with uniform
linear charge density , located a horizontal
distance D away.
a) First suppose that the nearby object is another
positive point charge Q, located a horizontal
distance D away.
