Question

Where does a body weigh more? At the sea level or on the mountains?

Answer 1

A body weigh more  at the sea level because weight decreases with altitude.

Answer 2

The object / body will weigh more at sea because the value of g / gravity is less due to it decreases with an increase in height. So, there is a less value of g at mountain level and thus it will weigh more at sea level than on mountain level .
