Question

Amit by a few gram of gold at the poles as per the instruction of ne of his friend .he hands over the same when he meets him at the equator. will his friend agree with the wight of gold bought ?if not,why?​

Answer 1

Answer:

No his friend will not agree with Amit handing over the gold.

Explanation:

Gravitational acceleration (g) varies inversely with R (radius), squared and also with changing values of lattiltude. Earth, which is an oblate spheriod, is flattened at the poles and slightly bulged at the equator.

For Re ( Radius at equator) > Rp ( Radius at poles),

Gp ( Gravitational acceleration at poles) > Ge ( Gravitational acceleration at equator ).

Now, Weight of gold = mg.

Therefore for greater values of g the weight of gold will be higher at the poles than the equator.

Hence the friend will not agree with the weight of the gold brought as it will turn out to be less than the original amount.
