Answer:
formula used K=F/∆l
∆l is the elongation of the spring
- F=10N
- ∆l=20mm===> 0.02m
- K=10N divided 0.02m= 500N/m

About Atom:</h3>
Atom consists of a central nucleus that is usually surrounded by one or more electrons .Each electron is negatively charged. The nucleus is positively charged and contains one or more relatively heavy particles known as protons and neutrons.
An early model of the atom was developed by the physicist Ernest Rutherford in 1913. He was the first to suggest that atoms are like miniature solar systems except that the attractive force is not caused by gravity, but by opposing electrical charged.

srry for short answer :)
Answer:
C : 1.4*10^(-11) N.
Explanation:
q_1 = q_2 = 1.6 * 10^(-19)
R^2 = (1)^2 + (4)^2 = 1.7 * 10^(-17) m^2
The coulomb's law is as follows:
F_e = k*q_1*q_2 / R^2
F_e = k*q^2 / R^2
F_e = (9.0*10^9) * (1.6 * 10^(-19))^2 / 1.7 * 10^(-17)
F_e = 1.35 * 10^(-11) N
Hence, answer closes to obtained is option C : 1.4*10^(-11) N.
