$(b)$ What is the value of $g$ on the surface of the earth?
$(c)$ On what factors does the value of $g$ depend?
(N/A) Acceleration due to gravity is the uniform acceleration produced in a body falling freely under the influence of the earth's gravitational pull,directed towards the center of the earth.
$(b)$ The average value of $g$ on the surface of the earth is $9.8 \, m/s^2$.
$(c)$ The value of $g$ depends on: $(i)$ The shape of the earth (it is greater at the poles and smaller at the equator),$(ii)$ Height above the surface of the earth (it decreases with altitude),and $(iii)$ Depth below the surface of the earth (it decreases as we move towards the center).
