Q11MDynamicsFree sample

A 0.10 kg0.10\text{ kg} mass is taken to Mars and then weighed on a spring balance and on a lever balance.
The acceleration due to gravity on Mars is 38%38\% of its value on Earth.
What are the readings on the two balances on Mars? (Assume that on Earth g=10 m s2g = 10\text{ m s}^{-2}.)

Options
