Mass

Two masses A and B, each of mass M are fixed together by a massless spring. A force acts on the mass B as shown in figure. If the mass A starts moving away from mass B with acceleration 'a', then the acceleration of mass B wil be :-

Fill in the blanks with appropriate words given below : Molecular mass is the _______ of atomic masses of elements present in a molecule. The mass of one mole of a substance in grams is called its _________ mass. The atomic masses represented in periodic table are their _______ masses.

We know that when two equal masses are placed on a line then, gravitational force on a third mass is zero due to these two masses when the third is placed at the centre of line joining the two masses. But if third mass is placed anywhere else on the x-axis, the gravitational force acts on that mass due to these two masses. Consider a system shown in figure. In this system two point masses of mass M each are placed at y-axis at a distance a from origin and these masses are fixed. If a third point mass of mass m is released at a distance x from origin on x-axis, then answer the following questions. The distance between positions of maximum force on mass m is

Considering a system having two masses m_(1) and m_(2) in which first mass is pushed towards centre of mass by a distance a, the distance required to be moved for second mass to keep centre of mass at same position is :-
