Activity 1: Direction: The following question is referring to the concept of Newton's Law of Gravitation on inferring gravitational force, weight, and acceleration due to gravity and Physical significance of gravitational field. Solve for the unknown quantities and round-off your final answers in the nearest hundredths. 1. A married couple is standing on a bus stop waiting for a ride. The wife and the husband have a mass of 65kg and 80 kg. respectively. Calculate the gravitational force that exist between them if they are 50cm apart from each other. 2. Planet A and Planet B have a mass of 4 x 1024 kg and 4.5 x 1025 kg. The gravitational force between the two planets is 4.8 x 1020. How apart is Planet A from Planet B
