Question 200: Gravitation

Question

A box weight 196 N on a spring balance at the north pole. Its weight recorded on the same
balance if it is shifted to the equator is close to (Take g = 10 ms–2 at the north pole and the radius
of the earth = 6400 km) :

Accepted Answer

At equator, weight
W = Mg - M$${\omega ^2}$$R
= 196 - $$\left( {19.6} ight){\left( {{{2\pi } \over {24 	imes 3600}}} ight)^2} 	imes 6400 	imes {10^3}$$
= 195.32 N
