Question

Define coulomb's law

Answer 1

Coulomb's law

Coulomb's law states that the force of interaction between two charges , which can be points shaped and stationary , depends directly on the product of magnitude of charges and falls inversely the square of distance between the charges.

F is directly proportional to q1q2/r^2

F = k q1q2/r^2

where k is the constant of proportionality which depends on the nature of surrounding medium and the system of measurement.

For SI,

k = 1/4π¢ = 9 × 10^9 Nm^2/C^2

Answer 2

Answer:

It is the force of attraction or repulsion between two charges which are at rest .

It is directly proportional to the product of the magnitude of the charges.

It is inversely proportional to the square of the distance between them.

k is the static force constant

$f \: = \frac{kq1q2}{ {r}^{2} }$
