22. A picture can be hung on a wall in three different ways, as shown. In each case, the string is draped over the nail such that the length and angle of the string on each side of the nail is the same, and thus the tension in both sides of the string are the same. In case I the strings make' an equilateral triangle with the top of the picture frame. In case II the strings are perpendicular to the top of the frame and in case 3 the strings form an isosceles triangle with the top of the frame. The tension in each side of the supporting string is: A) least in III B) greatest in I C) greatest in II D) greatest in III E) least in I T. II

D 2. A picture can be hung on a wall in three different
ways, as shown. In each case, the string is draped
over the nail such that the length and angle of the
string on each side of the nail is the same, and thus
the tension in both sides of the string are the same.
In case I the strings make an equilateral triangle
with the top of the picture frame. In case II the
strings are perpendicular to the top of the frame and in case 3 the strings form an isosceles triangle
with the top of the frame. The tension in each side of the supporting string is:
A) least in III
B) greatest in I
C) greatest in II
D) greatest in III
E) least in I
