The ratio of tensions in the string connected to the block of mass `m_(2)` in figure, respectively, is (friction is absent everywhere):`[m_(1)=50 kg, m_(2)=80kg` and `F=1000N]`

A

`7:2`

B

`2:7`

C

`3:4`

D

`4:3`

Text Solution

Verified by Experts

The correct Answer is:
3
In fig. (a)`1000-T_(1)=50a ` in fig(b)
`T_(1)-800=80a`
`1000+500-T_(2)=50a`
`T_(1)=12,000/13 " " T_(2)-800=80a`
`T_(2)=16,000/13`

Find the mass M so that it remains at rest in the abjoining figure. Both the pulley and string are light and friction is absent everywhere. (g = 10 m//s^(2))

As shown in Fig. three blocks connected together lie on a horizontal frictionless table and pulled to the right with a force F = 50 N. If m_(1)=5kg, m_(2)=10kg and m_(3)=15kg , find the tensions T_(1) and T_(2) .

Two blocks are connected by a massless string that passes over a frictionless peg as shown in Fig. 3E.46. One end of the string is attached to a mass m_(1) = 3 kg i.e. a distance R = 1.20 m from the peg. The other end of the string is connected to a block of mass m_(2) = 6 kg resting on a table. From what angle theta , measured from the vertical, must the 3 kg block be released in order to just lift the 6 kg block off the table ?

In each of the three arrangements, the block of mass m_(1) is being pulled left with constant velocity. There is no friction anywhere. The string are light and anextensible and pulleys are massless. The ratio of the speed of the block of mass m_(2) in the three cases respectively is:

Three blocks are connected as shown in figure on a horizontal frictionless table. If m_(1)=1kg , m_(2)=8kg , m_(3)=27kg and T_(3)=36N , T_(2) will be.

In the arrangement shown in the figure, friction exists only between the two blocks, A and B. The coefficient of static friction mu_(s)=0.6 and coefficient of kinetic friction mu_(k)=0.4 , the masses of the blocks A and B are m_(1)=20 kg and m_(2)=30kg , respectively. Find the acceleration (in ms^(-2) ) of m_(1) , if a force F=150N is applied, as shown in the figure. [Assume that string and pulleys are massless]

Two blocks of masses m and M are connected by an inextensible light string as shown in the figure. When a constant horizontal force F acts on the block of the mass M , then tension in the string is : (Assume that constact between the ground and the two blocks are frictionless) and blocks will not topple. (Given: m = 1 kg, M = 4 kg, F = 10 N, theta = 60^(@) )

Three blocks are connected as shown in fig. on a horizontal frictionless table if m_(1)=1 kg, m_(2)=8kg, m_(3)=27kg and T_(3)=36N, T_(2) will be:-
