System Of Particles And Rotational Motion-new Questions for CBSE Class 11th

When the angular velocity of a uniformly rotating body has increased thrice, the resultant of force applied to it increases by 60 newton. Find the acceleration of the body in two cases. The mass of the body, m = 3 kg

A man of 50kg is standing at one end on a boat of length 25m and mass 200kg. If he starts running and when he reaches the other end, he has a velocity 2ms -1 with respect to the boat. The final velocity of the boat is (in ms -1 )

Two bodies of masses 10 kg and 20 kg are located in x-y plane at (0, 1) and (1, 0). The position of their centre of mass is ………

Four particles, each of mass 1kg, are placed at the corners of a square OABC of side 1m. ‘O’ is at the origin of the coordinate system. OA and OC are aligned along positive x-axis and positive y-axis respectively. The position vector of the centre of mass is (in ‘m’)

A uniform wire of length L is bent in the form of a circle. The shift in its centre of mass is

Three identical spheres each of radius ‘R’ are placed touching each other so that their centres A,B and C lie on a straight line. the position of their centre of mass from A is
