The elevator shown in Fig. 6 is descending with an acceleration of 2m/s2. The massof the block A is 0.5 Kg and that of B is 1 kg. What force is exerted by the block A orblock B? What will be reading of the weighing machine if the blocks are kept on aweighing machine?4N, 1.2k

Answer»

If the elevator was stationary the force would be: mass×"g"Since the elevator is accelerating, the force is

m × (g - a) = .5kg × (9.81m/s²-2m/s²) = 3.9kgm/s² = 3.9 Newtons

thanx but can u pls also answer the second part
