Q. Consider the 668 N weight held by two cables shown below. The left-hand cable had tension T2 and makes an angle of pheta 2 with the ceiling. The right-handed cable had tension 550 N and makes an angle 45 degrees with the ceiling. The right hand cable makes an angle of 45 degrees with the ceiling and has a tension of 550 N.
what is the Tension T2 in the left- hand cable slanted at an angle of pheta 2 with respect to the wall? Answer in units of N
