Question

The figure shows a conical pendulum, in which a small object at the lower end of the string moves in a horizontal circle (the string describes a cone as the object rotates). The object has constant modulus velocity. The object's mass is m, the string has length L, and the circle has radius r. Neglect air resistance.

Consider the following statements:
i) the work of the weight force is negative.
II) the work of the pulling force on the string is zero.
III) the total work is zero.
Of these statements, only true are:

a)I
b)II
c)III
d)I and II
e)II and III
f)I and III
g)All
h)None
