A mass of 1 kg is suspended by a thread. It is (i) lifted up with an acceleration 4.9 m/s², (ii) lowered with an acceleration 4.9 m/s². The ratio of the tensions is (a) 3: 1 (b) 1: 3 (c) 1: 2 (d) 2: 1

Answer: (a). Lifted up: T₁ = m(g + a) = 1(9.8 + 4.9) = 14.7 N. Lowered: T₂ = m(g - a) = 1(9.8 - 4.9) = 4.9 N. T₁: T₂ = 3: 1, so the answer is (a).
