MCQs-PYQs-12th-jee

Two spherical bodies of masses m and 5m and radii R and 2R respectively, are released in free space with initial separation between their centres equal to 12 R. If they attract each other due to gravitational force only, the distance covered by smaller sphere just before collision is

MCQs-PYQs-12th-jee

A solid sphere rolls down two different inclined planes of same height, but of different inclinations. In both cases

MCQs-PYQs-12th-jee

A sphere rolls down on an inclied plane of inclination θ. What is the acceleration as the sphere reaches bottom ?

MCQs-PYQs-12th-jee

A ball rests upon a flat piece of paper on a table top. The paper is pulled horizontally but quickly towards right as shwon. Relative to its initial position with respect to the table, the ball

MCQs-PYQs-12th-jee

A solid sphere of mass I kg, radius 10 cm rolls down an inclined plane of height 7 m. The velocity of its centre as it reaches the ground level is

MCQs-PYQs-12th-jee

A solid disc rolls clockwise without slipping over a horizontal path with a constant speed v. Then the magnitude of the velocities of points A,B and C (see figure) with respect to a standing observer are, respectively,

MCQs-PYQs-12th-jee

A wheel is rolling along the ground with a speed of 2 ms^-1. The magnitude of the velocity of the points at the extremities of the horizontal diameter of the wheel is equal to

MCQs-PYQs-12th-jee

A solid cylinder 30 cm in diameter at the top of an inclined plane 2.0 m high is released and rolls down the incline without loss of energy due to friction. Its linear speed at the bottom is

MCQs-PYQs-12th-jee

The speed of a homogenous solid sphere after rolling down an inclined plane of vertical height h, from rest without sliding is:

MCQs-PYQs-12th-jee

A solid cylinder of mass M and radius R rolls without slipping down an inclined plane of length L and height h. What is the speed of its centre of mass when the cylinder reaches its bottom
