Gravitation Question 326
The value of acceleration due to gravity increases on moving from equator to poles
Options:
A) Decrease
B) increase
C) Remain the same
D) become halves
Show Answer
Answer:
Correct Answer: B
Solution:
Acceleration due to gravity (g) is given by $ g = \frac{GM}{r^2} $
$ [g=\frac{GM}{R^{2}}\Rightarrow g\propto \frac{1}{R^{2}}] $
As one moves from the equator to the poles, the radius of the earth decreases, hence g decreases.
