Answer:
2.304 * 10^-10N
Explanation:
The magnitude of the force is expressed as;
F = kq1q2/r²
k is the coulomb constant
q1 id the charge on the electron = -1.6*10^-19C
q2 is the charge on the proton = 1.6*10^-19C
k = 9*10^9
Substitute
F = (9*10^9)*( -1.6*10^-19)( 1.6*10^-19)/(1.00 10^-10)^2
F = 9*10^9*-2.56*10^-38/1.00 10^-20
F = -23.04*10^-29/1.00 10^-20
F = -23.04 * 10^(-29+20)
F = -23.04 * 10 ^-9
F = -2.304 * 10 ^ -10N
Hence the magnitude of the electric force between them is
2.304 * 10^-10N
