Question

How is Coulomb Law verified
How did Coulomb arrived to the equation
\[F=K\frac{Q_1 Q_2}{r^2}\]

Answer 1

:D

Answer 2

hehe ;)

Answer 3

:P

Answer 4

verified through experiments nd its not always valid
its valid for only static and point charges

and
\(F ∝ Q_1Q_2\)
\(F ∝\large \frac{1}{r^2}\)
so
\(F=K\large \frac{Q_1 Q_2}{r^2}\)

Answer 5

how it is checked on point charges!
to begin with what is meant by a point charge
how do you separate a single charge from a materiel and experiment on it

Answer 6

we can prove that its not valid for charges which are not point charges

for example take this case-

now when + charge moves to left and charge density increases on left and in \(F=k\frac{Q_1Q_2}{r^2}\)
the r that must be taken will be greater than our r as the overall charge moved left
so it wo't work
moreover we can say that when a electric force is applied then the body dipoles or distribution of charge may change due to polarization and it will affect the net force acting on body
