1.	Calculate the ratio of electric and gravitational force between two protons. Charge of each proton is 1.6 xx 10^(-19)C, mass is 1.672 xx 10^(-27)kg and G= 6.67 xx 10^(-11) Nm^(2) kg^(-2).
Answer» Solution :The electric force FE `(e^2)/(4piepsilon_(0)r^2)` The GRAVITATIONAL force `Fg = (Gm^2)/r^2` `:. (Fe)/(Fg)=1/(4piepsilon_(0))xxe^2/(m^2G) = 9XX10^(9)xx` `((1.6xx10^(-19))^2)/((9.1xx10^(-31))xx^(2) xx 6.67xx 10^(-11)) = 4.17 xx10^(42)`
