1 . Force is defined as rate of change in momentum, i.e

Now,

So,

Given,

So,acceleration =

2 . Weight of an object on the Earth means,the gravitational force with which the object is being pulled towards the earth.

So, for a particle of mass

or,we can write as,

Given,

So, its mass will be =
