Two blocks of mass 5 kg and 3 kg are attached to the ends of a string

1.	Two blocks of mass 5 kg and 3 kg are attached to the ends of a string passing over a smooth pulley fixed to the ceiling of an elevator. A man inside the elevator accelerated upwards, finds the acceleration of the blocks to be (9)/(32)g. The acceleration of the elevator is
Answer» `(g)/(3)` `(g)/(4)` `(g)/(8)` `(g)/(6)` Solution :( c) Let ACCELERATION of LIFT is a upwards. Then with respect to lif `a_(r)=("Net PULLING force")/("Total MASS")` `=((5g+ga)-(3g+3a))/(8)` `implies "" (9)/(32)g((g+a))/(4)` `therefore"" a=(g)/(8)`
