Identify the wrong statement in the following. Coulomb’s law correctly describes the electric force that

View answer and explanation

Correct option: B

Binds the protons and neutrons in the nucleus of an atom

Option B (Binds the protons and neutrons in the nucleus of an atom) is correct because Coulomb's law describes the electric force between charged particles, but the force binding protons and neutrons in the nucleus is the strong nuclear force.

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}
