Text Solution
Verified by ExpertsD
The gravitational force ( 
) between two electrons is calculated using Newton's Law of Universal Gravitation: 
, where 
is the gravitational constant ( 
), 
is the mass of an electron ( 
), and 
is the distance between the electrons ( 0.1 m ).
The electrostatic force ( 
) between two electrons is calculated using Coulomb's Law: 
, where 
is Coulomb's constant 
, 
is the elementary charge ( 
), and 
is the distance between the electrons (0.1 m).
Ratio of Forces
The ratio of the gravitational force to the electrostatic force is determined by dividing the expression for 
by the expression for 
.
The values are substituted into the ratio expression:
The calculation is performed: 
.
