Question

A particle of mass m is thrown horizontally from the top of a tower and another partide of mass 2m is thrown
vertically upward. The acceleration of centre of mass is​

Answer 1

Answer:

The acceleration for both the cases will be the constant g or 9.8m/s^2 in downward direction. This is because after the object is thrown only gravitational force acts on the 2 objects and according to universal law of gravitation (between earth and object.

F=G m1 M/d^2

m1 a=G m1 M/d^2

a=G Mass of Earth/radius^2

since the mass of object cancels on both the sides therefore the acceleration on the 2 objects doesn't depend on mass.
