The pulley arrangement in Fig are identical .The mass of the rope is negligble in figure the mass m is lifted up by atteched a mass `2m` to the other end of the rope . In (b), `m` is lifed up by pulley the other end of the rope with a constant in both cases

Text Solution

Verified by Experts

The correct Answer is:
False
For mass `m`
`T - mg = ma`….(i)
For mass `2m`
`2 mg - T - 2ma`….(ii)
From(i) and (ii) `a = g//3`
In second case` T- mg = ma'`
`2mg - mg = ma'`
`a' = g`

The pulley arrangements of Figs. (a) and (b) are identical. The mass of the rope is negligible. In (a) the mass m is lifted up by attaching a mass 2m to the other end of the rope. In (b), m is lifted up by pulling the other end of the rope with a constant downward force F=2mg . The acceleration of m is the same in both cases

The pulley arrangements shown in figure are identical, the mass of the rope being negligible. In case I the mass m is lifted by attaching a mass 2m to the other end of rope with a constant downward force F =2mg , where g is acceleration due to gravity The acceleration of mass m in case I is .

Figure shown two pulley arrangments for lifting a mass m . In case-1, the mass is lifting by attaching a mass 2m while in case-2 the mass is lifted by pulling the other end with a downward force F=2mg . If a_(a) and a_(b) are the accelerations of the two masses then (Assumme string is massless and pulley is ideal).

A pulley-rope-mass arrangement is shown in fig. Find the acceleration of block m_(1) when the masses are set free to move. Assume that the pulley and the ropes are ideal.

A uniform rope of length 10 cm and mass 4 kg hangs vertically from a rigid support. A block of mass 2 kg is attached to the free end of the rope. A transverse pulse of wavelength 0.06 m is produced at the lower end of the rope, what is the wavelength of the pulse when it reaches the top of the rope?

A rope thrown over a pulley has a on one of its ends and a counterbalancing mass M on its other end. The man whose mass is m , climbs upwards by vec/_\r relative to the ladder and then stops. Ignoring masses of the pulley and the rope, as well as the friction the pulley axis, find the displacement of the centre of mass of this system.

In the arrangement shown, the mass m will ascend with an acceleration ( Pulley and rope are massless)

In the arrangement shown, the mass m will ascend with an acceleration ( Pulley and rope are massless)
