![A block of mass m is hanging by two strings of negligible mass as shown in the figure.
String 1 is at an angle of 60° with the horizontal and string 2 at an angle of 45° with
respect to the horizontal. Find the magnitude of the force of tension in strings 1 and 2.
Express your answers in terms of m and g.
We recommend entering the exact value of trigonometric functions rather than their
decimal approximations. For example, you could enter:
T₁
