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) :
Solution
At equator, weight
<br><br>W = Mg - M${\omega ^2}$R
<br><br>= 196 - $$\left( {19.6} \right){\left( {{{2\pi } \over {24 \times 3600}}} \right)^2} \times 6400 \times {10^3}$$
<br><br>= 195.32 N
