Two electrons are separated by one cm. What is the ratio of the electric force to the gravitational force between them?
Note that Me = 9.11 x 10^-31kg, Ke=8.99 x 10^9 N m^2/ C^2 , G= 6.67 x 10^-11 N m^2/kg^2, e=1.6 x 10^-19 C, and Fg = G m1xm2/r^2
a)2.3 x 10^2
b) 1.3 x 10^20
c)3.1 x 10^22
d)4.2 x 10^42
