How far away can a proton and an electron be from each other, such that they still exert an electric force on each other of magn
pogonyaev

Answer:

\sqrt{ \frac{2.3 *10^{-28}     }{F} }

Explanation:

Total force = Force due to gravity + Force due to charges

Total force = \frac{GMm}{r^{2} } + \frac{kQq}{r^{2} }

r is the separation between particles.

Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs

Mass of a proton (M)= 1.67×10^-27 kilograms

Mass of an electron (m) =9.11 × 10^-31 kilograms

G=6.67 ×10^−11 N⋅m^2/kg^2

k=8.99 * 10 ^9 N.m^2 / C^2

Plugging in values:

Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67   /  r^2

Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28    /  r^2

We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.

Total force = Force due to charges.

F = 2.3 *10^-28    /  r^2

r = \sqrt{ \frac{2.3 *10^{-28}     }{F} }

andriy [413]
A psychologist would typically deal with the emotion problems of a person who don't suffer from serious disorders. A psychiatrist is a medical practitioner specializing in the diagnosis and treatment of someone who has a mental illness. They both help out when someone is desperately in need of it
