In the figure shown, the minimum force `F` to be applied perpendicular to the incline so that the block does not slide is

A

`200N`

B

`40 N`

C

`120 N`

D

none

Text Solution

Verified by Experts

The correct Answer is:
A

`f_l=muN=0.51[F-10g-cos37^@]`
`f=10gsin37^@`
For the block to not to slide `f_lgtf`.
`L implies0.51[F-10gcos37^@]gt10gsin37^@`
`implies Fgt200N`

Find out the minimum force that must be applied on the block vertically downwards so that the block doesn’t move.

In the figure shown, horizontal force F_(1) is applied on a block but the block does not slide. Then as the magnitude of vertical force F_(2) is increased from zero the block begins to slide, the correct statement is

A block of mas M is resting on an inclined plane as shown in the figure. The inclination of the plane to the horizontal is gradually increased. It is found that when the angle of inclination is theta the block just begins to slide down the plane. What is the minimum force F applied parallel to the plane that would just make the block move up the plane ?

A block of mass m is placed on a rough inclined plane. When the inclination of the plane is theta , the block just beging to slide down the plane under its own weight. The minimum force applied parallel to the plane, to move the block up the plane, is.

As shown in figure, if we apply a horizontal force F on the block, find the maximum force F (in N ) that can be applied so that block does not slide up. ( "Given" theta=45^(@),g=10m//sec^(2), m=1/5kg,mu=1/2)
