- Calculate the force Fnet= 0.1697(28-0)/.0791. Imagine bringing the tips of your index fingers together. Eachfinger contains a certain finite mass, and the distance betweenthem goes to zero as they come into contact. From the forcelaw F = Gm1m2>r2 one might conclude that the attractive forcebetween the fingers is infinite, and, therefore, that your fingersmust remain forever stuck together. What is wrong with thisargument?can this be rewritten in a legible way so i can understand how you got 335m
