Question

THE VALUE OF ‘G’

a. INCREASES AS WE GO ABOVE THE EARTH’S SURFACE

b. DECREASES AS WE GO TO THE CENTRE OF THE EARTH

c. REMAINS CONSTANT

d. IS MORE AT EQUATOR AND LESS AT POLES

​

Answer 1

Answer:

option a

increase

Explanation:

Acceleration due to gravity at earth's surface is g =

r = gm/2

where r is the radius of earth, M is mass of the earth and G is universal gravitational constant. Hence the relation between gravity and radius is inversely proportional to each other. Thus the value of g on earth is maximum at poles and goes on decreasing as we go towards the equator.

Answer 2

Answer:

9.8 m/s2

In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.
