Three blocks of masers and by massless strings as shown in figure, on a frictionless table. They are Pulled with the force . If and the tension will

Assertion  If  then 

Reason  If   is a homogeneous function in  of degree '  ' then 

For such questions, we should know the formulas related to homogeneous equation. Before solving the equation, we have to see if the given function is a homegenous function. A homegenous function has same degree for all its terms.

Two blocks of Nass and ane connected a heavy string placed on rough horizontal plane, the 4 kg block is Pulled with a constant force F. The co-efficient of friction between the blocks and the ground is , what is the value of F, So that the tension in the spring is constant throughout during the motion of the blocks?

A plate of mass is placed on a horizontal frictionless surface and a body of mass is placed on this plate, The coefficient of dynamic friction between this body and the plate is . If a force . is applied to the body of mass in along the horizonal direction the acceleration of the plate will be ……

Three forces are acting simultaneously on a particle mowing with velocity . These forces are represcaled in magnitude and dircction by the three sidcs of a triangle . The particle will now move with velocity…..

A body of 2 kg has an initial speed 5 m/s. A force act it for some time in the directive of motion. The force -me time (t) graph is shown in figure. The final speed of the body is

A force (F) varies with time (t) as shown in fig. Average force aver a complete cycle is

Fig shows the displacement of a particle going along X axis as a function of time. The force acting an the particle is zero in the region

A body of mass 6kg is hanging from another body af mass 10kg as shown in fig. This condition is being pulled up by a spring with an acceleration of . the tension is ,

A granophyre record is revolving with an angular velocity . A coin is placed at a distance r from the center of the record. The coefficient of static is. The coin will revolve if

We need to remember different formulas for this type of questions.

Two masses and M/2 are joincd togcther by means of light inexcusable string passed aver z, fictiodess pullcy as shown in fig. Whcn the bigger mass is rekasod, the small ane will ascend with an acceleration

A particle of mass is initially at rest. force acts on it whose magnitude changes with time. The force time graph is shown below,The velocity of the particle after is

A solid sphere of mass is resting inside a cube as shown in the figure. The cube is moving with a velocity Here is the time in scond. All surfaces are smooth. The sphene is at rest with respect to the cube. what is the total force exerted by the sphene on the cube (g=10ms^-2) )
