Take the effect of bulging of earth and its rotation in account. Consider the following statements:(A) There are points outside the earth where the value of g is equal to its value at the equator.(B) There are points outside the earth where the valus of g is equal to its value at the poles.(a) Both A and B are correct.(b) A is correct but B is wrong.(c) B is correct but A is wrong.(d) Both A and B are wrong. |

Answer» (b) A is correct but B is wrong. EXPLANATION: As we move towards poles the value of g starts increasing. Another fact is that as we go up at a place the value of g starts decreasing. So at any point on the surface of the earth where the value of g is more than at the equator, there will be points outside the earth (at some altitude) where the value of g will be equal to the value at the equator. So (A) is correct. On the surface of the earth, the value of g is maximum at poles. So we will not get the same value at higher up (outside the earth). |
