Question

If the earth stops rotating, the value of g at the equator ___________

(a) Increases

(b) Decreases

(c) No effect

(d) First increases and then decreases

I had been asked this question during an interview.

The doubt is from Gravitational and Gravity topic in division Gravitation of Engineering Physics I

Answer 1

Right answer is (a) Increases

For explanation I would say: At the equator, ge=g-Rω^2

When ω=0, ge=g

The value of g increases if the earth stops rotating.
