1.	A mass of 1 kg is suspended by a thread. It is lifted up with an acceleration 4.9m/s^(2) (ii) lowered with an acceleration of 4.9 mcdot s^(-2). The ratio of the tension on the thread is
Answer» `3:1` `1:2` `1:3` `2:1` Solution :Tension while lowering the MASS, `T_(2) = G - a = g - (g)/(2) = (g)/(2)` `therefore""T_(1) : T_(2) = (3g)/(2) : (g)/(2) = 3 : 1 ` Theoption A is correct.
