Spinning Globes and Apparent Weight

Can you show that ω must satisfy




for objects not to slip on the surface of a spinning spherical planet?

I am a retired physicist, who received his Ph.D. in theoretical physics decades ago, back when the Univax used ultra wide daisy-wheel printers, but after the age of the Punch Card. Before retiring, I spent over twenty years teaching undergraduate physics at the University level. I'm currently working on an Interactive Blog (www.PhysicsIntro.com/blog) -- a hobby of mine. Stop by if you get a chance.

Sincerely,
dr_k
