As per the request of one of his friends from the equator , Rahul buys 100 grams of silver at the north pole . He hands it over to his friend at the equator . Will the friend agree with the weight of the silver bought ? If not , why ?

Explanation

The weight of a body is given by W = mg , where m is the mass of the body and g is the acceleration due to gravity . g varies from place to place . The value of g at the equator is less than that at the north pole ( as well as the south pole ) . Hence , the weight of the silver bought at the north pole would be less when the silver is weighed at the equator . Therefore , Rahul's friend will disagree about the weight of the silver .
[ Note : The mass being independent of the value of g . Rahul's friends will agree about the mass of the silver . ]
