A painter is applying force himself to raise him and the box with an acceleration of `5m//s^(2)` by a massless rope and pulley arrangement as shown in fig Mass of painter is 100 kg and that of box is 50 kg if `g=10 m//s^(2)` then:

A

tension in the rope is 1125 N

B

tension in the rope is 2250 N

C

force of contact between the painter and the floor is 375 N

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A, C
For the system, the eqn. of motion is
`2T-(M+m)g=(M+m)a`
`2T=(M+m)(g+a)`
`2T=(100+50)(10+5)`
`T=1125 N`
For the painter the eqn. of motion is
`R+T=m(g+a)`
`R+1125=100(10+5)`
`R=375 N`

A painter is applying force himself to raise him and the box with an acceleration of 5(m)/(s^2) by a massless rope and pulley arrangement as shown in figure. Mass of painter is 100 kg and that of box is 50 kg. If g=10(m)/(s^2) , then:

A painter is raising himself and the crate on which he stands with an acceleration of 5m//s^(2) by a massless rope and pulley arrangement. Mass of the painter is 100 kg and that of the crate is 50 kg. If g=10m//s^(2) , then the (i) tension in the rope is 2250 N (ii) tension in the rope is 1125 N (iii) force of contact between the painter and the flow 750 N (iv) force of contact between the painter the paniter and the floor 375 N.

A man is raising himself and the crate on which he stands with an acceleration of 5ms^(-2) by a massless rope-and-pulley arrangement. Mass of the man is 100kg and that of the crate is 50 kg. If g=10ms^(-2) , then the tension in the rope is

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

A man of mass M stands on the floor of a box of mass m as shown in fig. He raises himself and the box with an acceleration a = g/3 by means of a rope going over a fixed frictionless pulley. If the mass of the rope is negligible compared to (M + m) and if M = 2m, the tension in the rope will be?

For the given figure the acceleration of 1 kg block if string is massless and mass of pulley is 2 kg and diameter of pulley is 0.2 m :-
