1.	A body weighs more at poles than at the equator of earth. Why ?
Answer» Earth is flattened at poles and bugled out at equator. Thereforce, polar radius `(R_(p))` is smaller than equatorial radius `(R_(e))`. As `g=(GM)/R^(2)`, and `R_(p) lt R_(e)` therefore, `g_(p) gt g_(e)` As `(W_(p))/(W^(e))=(mg_(p))/(mg_(e))` and `g_(p) gt g_(e) :. W_(p) gt W_(e)`.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
