If the earth suddenly stops rotating about its axis, what would be the effect on the value of ‘g’? Will this effect be same at all places?

Answer»

The value of ′g′ at a place on earth of latitude λ is g′ = g −\(R\omega^2\cos^2\lambda\).

For any value of ω, g′ < g. It means the value of ′g′ decreases due to rotation of the earth. If earth stops rotating, the value of g would increase. The effect will be maximum at equator and least at pole.
