The acceleration due to gravity g is plotted against the latitude  of a place. Out of the following, the one that best represents the graph is

a
b
c
d

detailed solution

Correct option is B

At a plant where angle of lattitude is Φ , g = gp - ω2 cos2Φ .Where gp = acceleration due to gravity at pole , R = radius of earth , w = angular velocity of spin of earth.At Φ = 00 , g = gp - ω2RAt Φ = 900 , g = gp
