Question

Determine the force between two free electrons space 10^-10 m apart in vacuum.

Answer 1

i would probably need to use the equation for coulombs law right? but i dont know how to set that up with the info im given

Answer 2

ok, do you know the charge of a free electron?

Answer 3

F = q₁q₂/(4πε₀r²) in Newtons
where ε₀ = 8.8542e-12 F/m = permittivity of space (Farad/meter)
Q is charge in coulombs
r is separation in meters
1 electron charge = 1.602e-19 C

plug in the numbers
