There blocks of masses `m_(1)` , `m_(2)` and `m_(3)` are connected by may less unstretchable strings on a smooth surface. Tension `T_(2)` is.

A

`10N`

B

`20N`

C

`32N`

D

`40N`

Text Solution

Verified by Experts

The correct Answer is:
C
`F_("net") =ma, T_(3) -T_(2) =m_(3) a, T_(2) -T_(1) =m_(2) a,T_(1) =m_(1)a`
solving the above equation, we get .

Three blocks of masses m_(1),m_(2) and m_(3) are connected by massless strings as shown on a frictionless table. They are pulled with a force T_(3)=40N . If m_(1)=10kg,m_(2)=6kg and m_(3)=4kg the tension T_(2) will be

Two blocks of masses m_(1) and m_(2) are connected by a massless spring and placed on smooth surface. The spring initially stretched and released. Then :

Three blocks of masses m _ 1 , m _ 2 and m_ 3 are connected by mass less string as shown kept on a frictionless table. They are pulled with a force T _ 3 = 40 N. If m _ 1 = 10 kg, m _ 2 = 6 kg and m _ 3 = 4kg , the tension T _ 2 will be

Two blocks of mass m_(1) and m_(2) (m_(1) lt m_(2)) are connected with an ideal spring on a smooth horizontal surface as shown in figure. At t = 0 m_(1) is at rest and m_(2) is given a velocity v towards right. At this moment, spring is in its natural length. Then choose the correct alternative :

Two blocks of masses m_(1) = 3 kg and m_(2) = (1)/(sqrt3) kg are connected by a light inextensible string which passes over a smooth peg . The blocks rest on the inclined smooth planes of a wedge and the peg is fixed to the top of the wedge . The planes of the wedge supporting m_(1) and m_(2) are inclined at 30^(@) and 60^(@) respectively , with the horizontal. Calculate the acceleration of masses and the tension in the string .

Three blocks of masses m_(1)=4kg, m_(2)=2kg, m_(3)=4kg are connected with ideal strings passing over a smooth, massless pulley as shown in figure. The acceleration of blocks will be (g=10m//s^(2))
