Two Blocks M₁ (= 0

question 51

Multiple Choice

Two blocks m₁ (= 0.4 kg) and m₂ (= 0.6 kg) are initially positioned at x = 0.6 and
X = 1.1m. One cord is used to couple the blocks together and another to attach m₁ to a vertical pole at the origin. The blocks are made to rotate in a horizontal circle on a frictionless surface. If the period of rotation is 0.4s then calculate the ratio of the tension for the inner cord divided by the tension in the outer cord.

• A) 0.64
• B) 1.4
• C) 1.6
• D) 0.74
• E) 1.8
