Give the Variation of acceleration due to gravity.

1.	Give the Variation of acceleration due to gravity.
Answer» Variation of acceleration due to gravity: (i) Effect of altitude: At a height h,: The value of g decreases with the increase in h. (ii) Effect of depth: At a depth d, : The value of g decreases with the increase in depth d and becomes zero at the centre of the earth. (iii) Effect of non-sphericity of the earth: The earth has an equatorial bulge and is flattened at the poles. So the value of g is minimum at the equator and maximum at the poles.

Answer»

Variation of acceleration due to gravity:

(i) Effect of altitude: At a height h,: The value of g decreases with the increase in h.

(ii) Effect of depth: At a depth d, : The value of g decreases with the increase in depth d and becomes zero at the centre of the earth.

(iii) Effect of non-sphericity of the earth: The earth has an equatorial bulge and is flattened at the poles. So the value of g is minimum at the equator and maximum at the poles.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
