Question

A wooden cube is weighed at the North pole by a beam balance and then by a spring balance.The reading on the beam balance is 6000g and the reading on the spring balance is 60N.At a point on the equator, the beam balance gives the same value while the spring balance records 59.8N.Explain this difference.

Answer 1

this is because a beam balance measures mass and mass does not vary place to place but spring balance measures weight which depends upon mass and acceleration due to gravity since Acceleration due to gravity is greater at poles than at equator so weight at North Pole is more than at equator
