Choose the correct alternative:
Acceleration due to gravity increases/decreases with increasing altitude.

उत्तर
Decreases
Acceleration due to gravity at depth h is given by the relation:
`g_h = (1-(2h)/Re)g`
Where,
`R_e` = Radius of the Earth
g = Acceleration due to gravity on the surface of the Earth
It is clear from the given relation that acceleration due to gravity decreases with an increase in height.
