A rock on Earth has a mass of 750 kg and a weight of 7,350 N. If the rock is taken into outer space, how will its mass and weight be affected?

• the weight and mass will remain the same because they are not altered by the affects of gravity

• the weight will remain the same, but the mass will change because of the effects of gravity

• the mass will be 76.5 kg, and the weight will increase because of the effects of gravity

• the mass will remain the same (750 kg), but the weight will decrease because of the effects of gravity.
