Mass on Two Strings



A block of mass M = 15 kg is suspended at rest by two strings attached to walls, as shown in the figure. The left string is horizontal and the right string makes an angle q = 50° with the horizontal. What is the tension in the left string? (Assume the ring where the strings come together is massless.)

Tleft = N
