A student must test the maximum force exerted on an object attached to a string before the string breaks. The student ties the object of mass m0 to one end of the string and then uses the other end of the string to spin the object at a constant speed so that the object travels in a horizontal circular path, as seen in Figure 1. Figure 2 shows the horizontal force exerted on the object at time t0. In a second trial, what should the student do to increase the tension in the string while keeping all other quantities constant? Select two answers.
