Law stating that “force is directly proportional to product of charges and inversely proportional to square of separation between them” is called

View answer and explanation

Correct option: B

Coulomb’s law

Option B (Coulomb’s law) is correct because Coulomb's law describes the electrostatic force between charges as directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

The ratio of magnitude of electric displacement (D) and electric field (E) is Gauss’s Law is valid for In hydrogen like system the ratio of coulombian force and gravitational force between an electron and a proton is in the order of: Statement-1:

\overrightarrow{{E}}

in outside velocity of a conductor depends only on the local charge density

\alpha

.
Statement-2:

\overrightarrow{{E}}

in outside vicinity of a conductor is given by

\frac{\sigma}{\varepsilon_0}

. Two charges each of 1 coulomb are at a distance 1

km

apart the force between them is

P \times 10^3
