Question

The earth's gravitational force causes an acceleration of 5m/so in 1kg mass somewhere in space. How much will be the acceleration of a 3kg mass at the same place.

Answer 1

the acceleration produced by the gravitational force does not depend on the mass of the object.so, acceleration produced in 3 kg object is equal to the acc. produced in 1 kg object.

g= GM/r²    

where G= gravitational constant

           M=mass of earth

           g= acceleration due to earth
