Answer:


(F1)/(F2)=5.4*
10^(26)

Step-by-step explanation:

Let

F1=Electric force

F2=Gravitational Force

F1=
(kq^(2) )/(r^(2) )

F2=
(Gm^(2) )/(r^(2) )


(F1)/(F2) =
((kq^(2) )/(r^(2) ) )/((Gm^(2) )/(r^(2) ) )


(F1)/(F2) =
(kq^(2) )/(Gm^(2) )


(F1)/(F2) =
(9*10^(9)*(20)^(2) )/(6.67*10^(-11) *(0.01)^(2) )


(F1)/(F2) = 5.4*
10^(26)
