Question

The Earth has been tilting on its axis for too long. It has decided to stand ramrod straight but continue its movements of rotation and revolution. What may or could happen in such a scenario?

Answer 1

Answer:

Here balancing forces,

Normal force+centrifugal force due tot earth's rotation=gravitational force.

Here, normal force is zero.

So, mg=mω

2

R⇒ω=

g/R

where m is the mass of the object, and R is the radius of planet.

The time period or duration of one day is then, T=2π/ω=2π

R/g
