Question

a body of 700g hangs from the end of a long wire fixed to a high tree. A horizontal string attached to the body pulls it until the wire is at 30° to the vertical. Find the tensions in both the string and the wire

Answer 1

You know two things: She sum of horizontal forces, and the sum of vertical forces is zero.
Horizontal forces: Let Fh be the tension in the horizontal wire, and Fw be the tension in the long wire .
Fh-Fw*sin30=0
Vertical forces:
.700*g -Fw*cos30=0
second equation first: Fw=.700*9.8/cos30
put that into the first equation and solve for Fh
