Question

Total electric flux emanating from a close surface, enclosing an alpha-particle and a deuteron (e = electronic charge) is​

Answer 1

Given:

A closed surface encloses an Alpha particle and a deuteron.

To find:

Total flux coming out of the closed surface.

Calculation:

As per Gauss'Theorem , the total flux coming out of any surface is equivalent to the ratio of the total charge enclosed and the permittivity of free space.

Net charge will be given by only Alpha particle because it's an ion and consists of +2e charge whereas deuteron is a neutral particle.

Considering Gauss' Theorem :

$\therefore \: \phi = \dfrac{q}{\epsilon_{0}}$

$= > \: \phi = \dfrac{2e}{\epsilon_{0}}$

So , final answer is :

$\boxed{ \sf{\: \phi = \dfrac{2e}{\epsilon_{0}} }}$
