Answer:
(a) The differences between
gravitational constant(G) and acceleration due to gravity (g) are
(b) The earth is not a perfect sphere.
The radius of earth increases from poles to the equator. Hence, as per relation
S. No.
Gravitational constant
(G)
Acceleration due to gravity
(g)
(i)
It is defined as the force of
attraction between two objects of unit mass each separated by unit distance.
It is defined as the acceleration of
an object freely falling under the action of force of gravity.
(ii)
It is an universal constant and its
value is
It is a constant at a given place its
value changes from place to place. Mean value of g on surface of earth is
value of g
i s greater at the poles and lesser at the equator. (1)
