A charge

q

is placed on a solid metallic object of irregular shape. Charge

q

will distribute itself.

View answer and explanation

Correct option: D

Non uniformly on the surface of metal

Option D is correct because excess charge on a conductor resides on its surface, and the distribution is non-uniform for irregular shapes due to varying curvature.

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

then value of

{P}

is Electric field due to point charge depends on distance
