A rod with a length ℓ and mass m extends horizontally from a wall. The rod is glued to the wall with very strong glue. A supporting cable is attached to the rod 0.45 of the way from the wall to the end of the rod. The cable extends straight up from the rod. If the tension in the cable is 0.20 times the weight of the rod (i.e. the tension is 0.20mg), how far from the wall is the center of mass of the rod?
Enter your result as the coefficient of ℓ rounded to two decimal places. For example, if your answer is 0.42ℓ, you would enter 0.42.
Enter 0.00 if there is not enough information.
Thank you and please take care!
