Answer:
Explanation:
Formula
Electric Force formula
F = k * q1 * q2 / r^2
Gravitation Force Formula
F = G * m1 * m2 / r^2
Givens
k = 8.99 * 10^9 N m^2/C^2
- N = newtons (units of force.
- m = meters
- c = coulombs (units of charge.
G = 6.67 * 10^-11 N m^2 /kg^2
- c_e = c_p = 1.6 * 19 Charge electron / Charge Proton
- m_e = 9.11 * 10^-31 Mass Electron
- m_p = 1.67 * 10^27 Mass Proton
Solutions
Fe = 8.99 * 10^9 * 1.6 * 10^-19 ^2/ 8.4 * 10^-11
The force = the electric force constant * the charge of the proton*charge electron/ distance apart in meters. It looks small but actually it is quite large in comparison to the Gravitational Force
Fe = 3.2 * 10^-8 (Answer First Box)
Fg = 6.67 * 10^- 11 * 9.11*10^-31 * 1.67*10^-27 / 8.4 * 10^-11
The gravitational Force is very small. Just look at the powers which come to 10^-68 - -22 = - 46 which is about 6 times smaller than the electric force.
Fg = 1.44 * 10^-47 (Answer Second Box)
