Question

Let w be the angular velocity of earth's rotation
about its axis. An object weighed by a spring
balance gives the same reading at the equator as at
a height h above the poles (h «<R). The height his
(g is acceleration due to gravity at poles)
'(1)w2*r2/g

(2) 2w²R²/g
(3)w^2r^2/2g

(4)w2r2/4g

​

Answer 1

Answer:

solve and get the answer

Explanation:

g' = g(1-2h/R) = g - w2r

Answer 2

Answer:

u looking so hot ❤️❤️❤️
