Three blocks having equal mass of are hanging on a string passing over a pulley as shown in figure. whal will be the tension prodoced in a string connccting the blocks B and C.

A bag of sand of mass m is suspended hy rope. A bullet of mass m/30 is fired at it with a velocity v and gets embedded into it . The velocity of the bag finally is

Three blocks A,B, and C of equal mass are placed one over the other, one on a smooth horizontal ground as shown in figure. Cefixime of friction between any two blocks of A,B and is 0.5. What would he the maximum value of mass of block D so that the blocks A,B and C move without slipping over each other '?

body of mass m rests on horizontal surface. The coefficient of friction between the body and the surface is if the body is pulled by a force P as shown in figure the limiting function between body and surface will be

A satellite of mass m is orbiting close to the surface of the earth (Radius R=6400 km ) has a K.E. K. The corresponding K.E. of satellite to escape from the earth's gravitational field is

Three masses and are connccied to cach other with threads and are placed on a table as shown in figure. The alcceleration with which the system is moving is

If the surfaces shown in figure are frictionless, the ratio of and is

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 ,
