seema buys few grains of gold at the poles as per the instructions of one of her friends. She hands over the same when she meets her at the equator . Will the friend agree with the weight of gold bought ? If not , why?
hre friend will not agree with the gold brought as the accelaration due gravity is greater at poles. so, weight of anything on the poles will be greater than that on the equator. this is because of the reason that equator has a greater distance from the centre of the earth than the poles.
