5. ropes 3 m and 5 m in length are fastened to a holiday decoration that is suspended over a town square. the decoration has a mass of 5 kg. the ropes, fastened at different heights, make angles of 52 and 40 with the horizontal. find the tension in each wire and the magnitude of each tension. hint: the lengths of the wires have nothing to do with the tension in each wire. slader

Explanation:

Let T1 be the tension in rope of length 3 m and T2 be the tension in the rope of length 5 m.

Mass = 5 kg

Resolve the components of T1 and T2 and maintain the equilibrium in vertical and in horizontal direction.

First take equilibrium in horizontal direction:

0.788 T1 + 0.642 T2 = 49 .... (1)

Take the equilibrium in horizontal direction

-0.62 T1 + 0.766 T2 = 0    .... (2)

By solving equation (1) and (2) we get

T2 = 30.26 N

T1 = 37.53 N

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
