A conductor has been given a charge

- 3 \times {10^{ - 7}}C

by transferring electrons. Mass increase (in kg) of the conductor and the number of electrons added to the conductor are respectively

View answer and explanation

Correct option: D

2 \times {10^{ - 18}}\;\mathrm{and\;}2 \times {10^{12}}

Option D (

2 \times {10^{ - 18}}\;\mathrm{and\;}2 \times {10^{12}}

) is correct. It involves calculating the number of electrons transferred and the corresponding mass increase using the charge and mass of a single electron.

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
