Find the weight of the same object on a planet where the gravitational attraction has been reduced to 1/10 of the earth's pull

I'm dumb

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

How are the crust and the inner core alike? a) they are both solid. b) they both have the same temperature. c) they are both under the same pressure. d) they are both very close to the center of the earth.

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight
