As the object is falling freely, the acceleration of the object will be equal to the acceleration due to gravity.

It is given as,

[tex]g=\frac{GM}{R^2}[/tex]

Here, G is the univarshal gravitational constant and M is the mass of the Earth.

means acceleration of the object is constant and independent of the mass of the object.

so option 1 is correct.

now the gravitational force on that object is,

[tex]F=\frac{GMm}{R^2}[/tex]

here this is dependent on the mass of the object(m).

NOw the gravitational field means the force per unit mass and is given by,

[tex]E=\frac{GM}{R^2}[/tex]

Here we can se that this gravitational field is also independent of the mass of the object.

So, option 1 and 4 are correct.
