Question
Hello. I received this problem in my physics class that I had problems with. We are on the chapter dealing with gravitation. Could you be so kind as to work me through it with as simple steps as possible so that I may follow along? I apologize for the multiple parts. Thank you!
G 7 x 10-11 (N m2)/(kg2) 2 a 1. a) Calculate the gravitational force between two students, one of 50 kg and one of 60 kg, considering that the distance between the centers of mass is 1 m. b) Calculate the gravitational force between an apple of mass 100 g and Earth, considering the distance between the center of the Earth and the apple the average radius of the Earth. M 5.972 x 1024 kg, radius r km. c) What fraction of the gravitational force apple-Earth does the gravitational force student- student represent?Explanation / Answer
Using the given relation
a) F = 6.67*10-11*50*60/12 = 2.001*10-7N
b) F' = 6.67*10-11 * 0.1*5.972*1024/(6371*103)2 = 0.98136 N
c) F/F' = 2.04*10-7
