Detailed Solution

The acceleration of the object of mass

3 kg

due to the influence of gravity will be

9.81 m / s^{2}

.
Acceleration due to gravity is the term used to describe an object's acceleration as a result of gravitational force. It has a SI unit of

m / s^{2}

. It has both a direction and a magnitude, making it a vector quantity. Gravitational acceleration is represented by the letter

g

. On the surface of the earth,

g

has a standard value of

9.8 m / s^{2}

. The acceleration due to gravity acting on every object will be the same. Hence both masses will have the same acceleration as they fall.
