Two forces F(1) " and " F(2) are acting...

Two forces ` F_(1) " and " F_(2)` are acting on a rod abc as shown in figure.

A

`(g)/(3l)`

B

`(g)/(13l)`

C

`(g)/(2l)`

D

`(7g)/(3l)`

Text Solution

Verified by Experts

The correct Answer is:
B

`tau_(P)=I_(P)alpha rArr 5m_(0)g l-4m_(0)g l= (5m_(0)l^(2)+2m_(0)(2l)^(2))alpha`
`rArr alpha=(m_(0)gl)/(13m_(0)l^(2))=(g)/(13l)`

Two forces of mangitude F_(1) and F_(2) are acting on an object.The magnitude of the net force F_(n e t ) on the object will be in the range.

Initially both blocks are at rest on a horizontal surface and string is just tight. At t=0, two constant horizontal force F_(1) and F_(2) start acting on blocks as shown. f_(1) and f_(2) are frication foces acting on 10 kg and 20 kg block (co-efficient of frication between and ground are 0.5 ). Values of F_(1) and F_(2) are given column-I. Then match magnitudes of f_(1), f_(2) and direction of overset(vec)(f_(1)) with corresponding values of F_(1) and F_(2) given in column-I [g = 10 m//s^(2)] .

A block is kept at rest on a rought ground as shown. Two force F_(1) and F_(2) are acting on it. If we increased either of the two force F_(1) and F_(2) , force of friction acting on the block will increase. By increasing F_(1) , normal reaction from ground will increase.
