ACCELERATION DUE TO GRAVITY BELOW AND ABOVE THE SURFACE OF EARTH

True-False Question

a

Graph shows variation of Acceleration due to gravity (g) from the centre of the Earth (radius R)

g and gd are Acceleration due to gravity at the surface of the Earth (R) and at a height equal to radius of the Earth (2R) respectively

Question 1

Acceleration due to gravity (g) is maximum at the surface of the Earth

Question 2

Acceleration due to gravity (g) is zero at the centre of the Earth

Hint

Varies with the factor

g

If d = R, gd = ?

Question 3

In the figure g = 9.8 m/s2, then at an altitude equal to radius of the Earth (h = R), the Acceleration due to gravity gd = 4.9 m/s2

Hint

g

At R = h, g(h) = ?

Question 4

Acceleration due to gravity decreases linearly with increase in depth

Hint

See region I in the figure

Question 5

Acceleration due to gravity decreases linearly with increase in altitude

Hint

See Region III in the figure
