A body weighs less at the equator than at the poles because —

[ A ] Earth rotates about its axis
[ B ] The ice-cap at the pole increases gravitational pull
[ C ] Equatorial diameter is greater than polar diameter
[ D ] Of some unknown fact

Answer : Option A

Explanation :

At the equator the earth bulges so its radi us i s more and gravi ty which multiplies mass to give weight varies according to this formula g= $GM\over r^2$ So, you can see that from the equation the value of “g” reduces with increased radius, so the less the “g” the less the “weight” since mass is constant.
