A spring balance operates by the extension of a spring. It has been calibrated on Earth in kilograms.
A beam balance operates by balancing standard masses against the unknown mass to be measured.
The same unknown mass is measured with each balance on Earth and on Mars.
The gravitational field strength on Mars is less than that on Earth.
How would the measurements on Mars compare with those on Earth?
Spring balance: smaller on Mars than on Earth; Beam balance: smaller on Mars than on Earth
Spring balance: smaller on Mars than on Earth; Beam balance: same on Mars as on Earth
Spring balance: same on Mars as on Earth; Beam balance: smaller on Mars than on Earth
Spring balance: same on Mars as on Earth; Beam balance: same on Mars as on Earth
