An object, moving along the
circumference of a circle with radius R, is acted upon by a force
of constant magnitude F. The force is directed at all times at a 30
angle with respect to the tangent to the circle as shown in the
figure .
Determine the work done by this force when
the object moves along the half circle from A to B.
Express your answer in terms of the
variables , , and appropriate constants.
