Weight of a body on the Earth is given by W = mg Where, m = Mass of the body g = Acceleration due to gravity The value of g is greater at poles than at the 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. FRead more
Weight of a body on the Earth is given by W = mg
Where,
m = Mass of the body
g = Acceleration due to gravity
The value of g is greater at poles than at the 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.
Gravitational force between the earth and an object is known as the weight of the object. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-10/
Gravitational force between the earth and an object is known as the weight of the object.
When objects fall towards the Earth under the effect of gravitational force alone, then they are said to be in free fall. Acceleration of free fall is 9.8 ms−2, which is constant for all objects (irrespective of their masses). For more answers visit to website: https://www.tiwariacademy.com/ncert-soRead more

Amit buys few grams of gold at the poles as per the instruction of one of his friends. He hands over the same when he meets him at the equator. Will the friend agree with the weight of gold bought? If not, why? [Hint: The value of g is greater at the poles than at the equator.]
