Question

A pulley is attached to the ceiling of a lift moving upwards two particles are attached to the two ends of a string passing over the pulley the masses of the particles are in the ratio 2 : 1 if the acceleration of the particles is g/2 then acceleration of the lift will be

Answer 1

Answer:

The acceleration of the lift will be g/2

Explanation:

According to the problem the pulley is attached to the ceiling of a lift moving upwards.

Let the acceleration of the lift is a

Two particles having the mass ration of 2:1

If we consider that the heavier mass will be accelerated downward and lighter will go upward

Then for the heavier mass acceleration will be (a - g/2)

for lighter mass (a + g/2)

T - 2m*g = 2m*(a - g/2) .....(i)

T - m*g = m*(a + g/2)....(ii)

Now by subtracting both equation

a = g/2

Answer 2

Answer: The answer is g/2.
