Question

How would Coulomb's Law be written if the charge of an electron was instead defined as positive and the proton as negative?F = -kQq/r2F = kQq/r2F = -kQ/r2F = kq/r2

Answer 1

Given,

Electron are positive and the charge can be considered as q.

Proton are negative and the charge can be considered as -Q.

Thus the coloumb's law is

`\begin{gathered} F=k(q(-Q))/(r^2) \\ \Rightarrow F=-k(qQ)/(r^2) \end{gathered}`

The answer is:

`F=-k(qQ)/(r^2)`
