Please help me to understand this questions and solve the problems.
0=hMass(6) The student performs several trials in order to vary the value of r. Remember that on each individualthe beads all have the same radius r from the center, but that radius changes from one trialtrial to the next. Thstudent takes data of the acceleration a of the block and the tension T in the cord supporting the bloey Theach trial, and plots these quantities as a function of r. The two graphs are shown below.RRGraph 1Graph 2Which of the two graphs shown in the graph of acceleration as a function of radius r?Graph 1Graph 2Explain why this graph is the acceleration vs. radius graph.ii. Explain why the other graph is the tension vs. radius graph.(c) The final trial that the student took was the trial on which r = R (i.e. the beads were set on thethe wheel).i. Which of the following best describes the tension T in the cord for this trial?T < mgT= mgT> mgExplain your reasoning.
