Use coulomb's law, f=kq1q2/d2, to calculate the electric force on an electron (q=−1.6×10−19c) exerted by a single proton if the particles are 0.53×10−10m apart. the constant k in coulomb's law is 9.0×109 n⋅m2/c2. (the unit abbreviated n is the newton, the si unit of force.) express your answer using two significant figures.

Respuesta :

Electrostatics force is given by

[tex]F = \frac{kq_1q_2}{r^2}[/tex]

[tex]F = \frac{9*10^9 * 1.6 * 10^{-19}* 1.6 * 10^{-19}}{(0.53* 10^{-10})^2}[/tex]

[tex]F = 8.2 * 10^{-8} N[/tex]

so above is the force between proton and electron
