Question

Amit buys few grams of gold at the poles as for the construction of one of his friend his hands over the same when he meets him at the equator will the friend happy with the weight of gold what if not why
(Hint the value of g is greater at the poles than at equator)

Answer 1

Answer:

No

Explanation:

the friend will not be happy because the g is greater at poles than at equator

let the distance of equator from center of earth be Re and of the pole be Rp

Now ,

Re > Rp

Also wt. of gold at equator= M(Gold) * ge = G*M(earth)*M(gold)/Re^2

        wt. of gold at pole= M(Gold) * ge = G*M(earth)*M(gold)/Rp^2

because Re > Rp

=> 1/Re^2 < 1/Rp^2

hence

Wt. of gold at equator < Wt. of the gold at pole

SYOURANSWER

:-

Since, W = mg

And, the value of g is greater at poles than at equator.

Therefore, gold at the equator weighs less than at the poles.

Hence, Amit's friend will not agree with the weight of the gold bought.
