A 75.0 kg astronaut is standing on the surface of Venus. The mass of Venus is 4.87 x 1024 kgand the radius of Venus is 6.05 x 106 m (which is less massive and smaller than the Earth).(a) What is the weight of the astronaut on Venus? Include the direction as well. (b) What isthe acceleration due to gravity at the surface of Venus? (c) What is the weight of theastronaut on Earth? (d) Include a diagram of the situation.
