charge_tutorialHW...
1. Two identical metal balls are
suspended by insulating
threads. Both balls have the
same net charge. In this
problem, do not assume the
balls are point charges.
C.
Draw a separate free-body
diagram for each ball. Label the forces to
indicate:
• the object exerting the force,
• the object on which the force is exerted,
• the type of force (gravitational, normal,
etc.), and
• whether the force is a contact or a non-
contact force.
Predict whether the angle
that ball 1 makes with the
vertical will be greater
than, less than, or equal to
the angle that ball 2 makes
with the vertical. Explain.
Sketch your answer at right.
Predict what will happen if
the net charge on ball 2 is
reduced to zero. Make a
sketch to illustrate your
answer.

How does the free-body diagram for each ball in this case compare to the corresponding free-
body diagram that you drew in part a? If the magnitudes or directions of any of the forces are
different, describe how they differ.
