A 0.10 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% of its value on Earth. What are the readings on the two balances on Mars? (Assume that on Earth g = 10ms⁻².)
Aspring balance/N 0.38, lever balance/kg 0.038
Bspring balance/N 0.38, lever balance/kg 0.10
Cspring balance/N 1.0, lever balance/kg 0.038
Dspring balance/N 1.0, lever balance/kg 0.10
