Question 01: 126 Marksl 1.1. A small block of mass m attached to the end of a string revolves in a circle on a frictionless table top. The other end of the string passes through a hole in the table. Initially, the block revolves with a speed vi - 3.4 m/s in a circle of radius R₁ = 0.95 m. The string is then pulled slowly through the hole so that the radius is reduced to R2 = 0.58 m. the initial tension is T, and the final tension is T2. 1.1.1. Name the two types of forces and give one example to each. 1.1.2. Use the conservation of angular momentum to find v2. 1.1.3. Show that the tension T2 is greater than T₁ by a factor of about four.
someone please help especially with 1.1.3
