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
