Q. Two blocks are placed in contact on a horizontal frictionless surface. The smaller box has less mass than the larger box. A force F is applied to the small box as shown so that the boxes accelerate to the right. Which box has the biggest net force acting on it? A box is suspended from the ceiling by two ropes making an angle with horizontal. What is the tension in each rope?
