1.	A mass of 1 kg is suspended by a thread. It is (i) lifted up with an acceleration of 4.9mcdot s^(-2).
Answer» `3:1` `1:2` `1:3` `2:1` Solution :Weight of the BODY = mg (DOWNWARDS) Tension on the thread = T (upwards) `THEREFORE` Resultant force acting on the body = T - mg (UPWARD) If a si the upward acceleration then from F = ma we get. T - mg = MAOR, T = m(g + a)
