An object is weighed at the North pole by a beam balance and a spring balance, giving readings of WB and WS respectively. It is again weighed in the same manner at the equator, giving reading of W′B and W′S respectively. Assume that the acceleration due to gravity is the same everywhere and that the balances are quite sensitive.
WB=WS
W′B=W′S
WB=W′B
W′S<WS
A

B
W′B=W′S
C
W′S<WS
D
WB=W′B

Let ω be the angular velocity of the earth's rotation about its axis. Assume that the acceleration due to gravity on the earth's surface has the same value at the equator and the poles. An object weighed by a spring balance gives the same reading at the equator as at a height h above the poles (h<<R). The value of h is
