Application +4 | -1

An electron enters in high potential region

{V_2}

from lower potential region

{V_1}

then its velocity

View answer and explanation

Correct option: A

Will increase

Option A (Will increase) is correct because an electron moving from a lower potential to a higher potential region gains kinetic energy, thus increasing its velocity.

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
