The acceleration due to gravity is `g` at a point distant `r` from the centre of earth of radius `R`. If `r lt R`, then

If g denotes the value of acceleration due to gravity at a point distance r from the centre of earth of radius R . If r lt R , then

The dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to be sphere of radius R of uniform density is a shown in figures along side. The correct figure is

The dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to br a sphere of radius R of uniform density is as shoen in Fig. below: The correct figure is

If R= radius of the earth and g= acceleration due to gravity on the surface of the earth, the acceleration due to gravity at a distance (r lt R) from the centre of the earth is proportional to

If R= radius of the earth and g= acceleration due to gravity on the surface of the earth, the acceleration due to gravity at a distance (r gt R) from the centre of the earth is proportional to

Variation of acceleration due to gravity (g) with distance x from the centre of the Earth is best represented by (R to Radius of the Earth)

The acceleration due to gravity at a depth R//2 below the surface of the earth is

If acceleration due to gravity at distance d [ < R ] from the centre of earth is beta , then its value at distance d above the surface of earth will be [ where R is radius of earth ]

The value of the acceleration due to gravity is g1 at a height h=(R)/(2)(R= radius of the earth) from the surface of the earth.It is again equal to (g1/2) at a depth d below the surface of the earth.The ratio d/R equals:
