This is urgent. I will appreciate

Question 11 11.1 The centre of mass m₁ is located at distance r from the centre of mass m₂, and m₁ undergoes a circular motion at speed, v, due to m₂. Upon doubling the magnitude of m₁ and halving the separation distance between the centres of the two masses, what shall the speed of m₁ become in terms of v? (Show the workings; i.e. show how you get the answer.) 11.2 A 120 g mass, attached to 20 cm long string, undergoes vertical circular motion at 1.7 m.s¹¹. Determine the tension on a string at an instant when the stone is 150 mm above the lowest point of its motion. (Ignore the diameter of the stone)
