If Max weighed 17.2 N on Ceres (gravitational field strength of 0.27 N/kg), then what would she weigh on Earth. Give your answer to 3 s.f. and state your units.

For this question you only need to know one equation, however, what is key is to be able to understand what the question is asking for and how to go about it.Weight is the force applied to a body due to the gravitational force of another body, Ceres in this context. The equation to calculate weight is: weight = mass * gravity.The question is asking for the weight of Max on Earth. We already know the gravitation field strength of Earth (9.81 N/kg) and so we only need to know Max's mass. We can calculate this using the same equation, and the information given in the equation.She weighs 17.2N on Ceres (where g = 0.27 N/kg), so rearranging the weight equation for mass: m = W / g, we get Max's mass to be 17.2 / 0.27 = 63.703703... kg.Putting this back into the weight equation to calculate her weight on Earth: 63.703703... * 9.81 = 624.933333... N.Reducing this to 3 significant figures, and remembering to include the units for weight (Newtons), the final solution is: 625 N.
