The electric field created by a point charge falls with distance

r

from the point charge as

View answer and explanation

Correct option: B

\frac{1}{{{r^2}}}

Option B is correct because the electric field due to a point charge is inversely proportional to the square of the distance from the charge, as described by Coulomb's Law.

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}
