Answer 2

Explanation:

Effect of rotation of earth on acceleration due to gravity, g

λ =ge −Re

w2 cos2 λ where w is the angular velocity of the rotation of earth and λ is the lattitude.

Now at equator, λ=0

o ⟹gλ=ge −Re w 2

Thus as the spinning speed of earth increases, then g at equator decreases and thus weight of body decreases at equator.
