Two particles of mass 2 kg and 4 kg lie on the same line. If 4 kg is displaced rightwards by 5m then by what distance 2 kg should be move for which centre of mass will remain at the same position

Two particles of mass 1 kg and 2 kg lie on the same line. If 2kg is displaced 10m rightwards then by what distance 1kg should displaced so that centre of mass will displaced 2m right wards.

Two particles of masses 10 kg and 30 kg are lying on a straight line. The 10 kg mass is shifted towards the 30 kg mass by a distance of 2cm. By what distance should the 30kg mass be shifted so that the position of their centre of mass does not change

Two particle of mass 2 kg and 1 kg are moving along the same straight line with speeds 2m//s and 5m//s respectively. What is the speed of the centre of mass of the system if both the particles are moving (a) in same direction (b) in opposite direction ?

Two particles of mass 1kg and 2kg are moving along the same line with speeds 2m//s and 4m//s respectively. Calculate the speed of the centre of mass of the system if both the particles are moving in the same direction.

Two particles of mass 1kg and 2kg are moving along the same line with speeds 2m//s and 4m//s respectively. Calculate the speed of the centre of mass of the system if both the particles are moving in the same direction.

Two particles of mass 1kg and 2kg are moving along the same line with speeds 2m//s and 4m//s respectively. Calculate the speed of the centre of mass of the system if both the particles are moving in the same direction.

Two bocks of masses 10 kg and 20 kg are placed on the X-axis. The first mass is moved on the axis by a distance of 2 cm. By what distance should the second mass be moved to keep the position of the centre of mass unchanged?
