Question
a.the gravitational force between 2 electrons 1.00m apart is 5.42x10^-71 N. Find the mass of an electron.
b.2 spherical balls are placed so their centres are 2.6m apart. The force between the balls is 2.75x10^-12N. What is the mass of each ball if one ball is twice the mass of the other ball?

Answers
(a) Solve F = 5.42x10^-71 N = G*m^2/(1)^2
m is the electron mass and g is the universal cnstant of gravity.
That equatiuon can be solved for m.
(b) Let the ball masses be M and 2M
F = 2.75x10^-12N = G*(2M^2)/(2.6)^2
Solve for M

(b) Let the ball masses be M and 2M
F = 2.75x10^-12N = G*(2M^2)/(2.6)^2
Solve for M
234 N
