An object weighs 39.36 newtons. What is its mass if a gravitometer indicates that g = 9.83 m/s2?

4.0 kg

386.9 kg

0.3 kg

The force applied to an object is said to be a product of its mass and the acceleration. For this case, acceleration is the reading on the gravitometer. We calculate as follows:

F = mg

39.36 N = m (9.83 m/s^2)

m = 4.00 kg

Hope this answers the question. Have a nice day.
