Question

Find force between a proton and an electron placed at the distance 1 mue metres

Answer 1

Answer:

230.4 * 10⁻³¹ N.

Explanation:

Charge of an electron = 1.6 * 10⁻¹⁹ C.

Charge of a proton = 1.6 * 10⁻²⁷ C.

F = k*q₁*q₂ / r²

F = 9*10⁹ * 1.6*10⁻¹⁹ * 1.6*10⁻²⁷ / 1 * 10⁻⁶

F = 25.6 * 9 * 10⁻³⁷ * 10⁶

F = 230.4 * 10⁻³¹ N.
