Hello, please solve this task and clearly explain the solution with image. Thank you in advance

Problem 2 25 ptsl An object of mass m = 0.25 kg, rotating on a string along a circular path of radius R = 0. 7 m in the vertical plane, subjects to gravitational force (see gure at the right). The maximum tension force that the string can sustain without breaking is 30 N. If the speed of the object is being slowly increased (it means that the tangential acceleration is negligibly small compared to centripetal one), and assuming g = 9.8 m/SJ, answer the following: 2.1. Find the position of the mass on the circular trajectory (exactly) where the string has maximum tension at a given constant speed of the mass. (10 pts) 2.2. What is the maximum speed (m/s, round to 1 decimal place}, when the string does not break for any position of the object on the whole circle trajectory? (15 pts)
