The earth's gravitational force causes an acceleration of 5 ms−2 in a 1 kg mass somewhere in space. How much will the acceleration of a 3 kg mass be at the same place?
The acceleration produced by the gravitational force of earth does not depend on the mass of the object. So, the acceleration produced in the 3 kg mass will be the same as that produced in 1 kg mass i.e. 5 ms−2.
