Find the electric force between two protons separated by a distance of 1 fermi `(1fermi = 10^(-15)m).` The protons in a nucleus remain at a separation of this order.

Options

A. 230N
B. 2300N
C. 23000N
D. None of the Above

Answer

A

Explanation

`Charge on each proton =1.6xx10^-19 `
` Coulomb `
` Distance between the charges=10^-15m `
` F_e=(1)/(4piepsilon_0)xx(q^2)/r^2 `
` =(9xx10^9)xx(1.6xx10^-19)^2/(10^-15)^2 `
` =230N`
