An object is weighted at the North Pole ...

An object is weighted at the North Pole by a beam balance and a spring balance, giving readings of `W_B` and `W_S` respectively. It is again weighed in the same manner at the equator, giving readings of `W'_B` and `W'_S` respectively. Assume that the acceleration due to gravity is the same everywhere and that the balance are quite sensitive, Choose the wrong option

A

`W_(B)=W_(S)`

B

`W'_(B)=W'_(S)`

C

`W_(B)=W'_(B)`

D
