One block of 2.0 kg mass is placed on top of another block of 3.0 kg mass. The coefficient of static friction between the two blocks is 0.2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking g = 10 m/s², the maximum value of the frictional force is:

Two persons are holding a rope of negligible mass horizontally. A 20 kg mass is attached to the rope at the midpoint; as a result the rope deviates from the horizontal direction. The tension required…

The power required to lift a mass of 8.0 kg up a vertical distance of 4 m in 2 s is (taking acceleration due to gravity as 10 m/s²):

A particle is found to be at rest when observed from a reference frame S1 and the same particle is found to move with a constant velocity when observed from another frame S2. Which of the following s…

Given below are two statements, one is labelled as Assertion (A) and other is labelled as Reason (R). Assertion (A): In simple harmonic motion, the potential energy of the particle is maximum at the…

An object is launched horizontally from a height of 45 m above the ground with a speed of 10 m/s. The time at which the object will hit the ground is: (Take g = 10 m/s²)
