The total electric flux emanating from a closed surface enclosing an alpha particale (e = electronic chage) is

A

`(2e)/(epsilon_(0))`

B

`(e)/(epsilon_(0))`

C

`(epsilon_(0)e)/(4)`

D

`(4e)/(epsilon_(0))`

Text Solution

Verified by Experts

The correct Answer is:
A
According to Gauss.s law
Electric flux, `phi_(E) = (q_("inside"))/(epsilon_(0))`
Charge on `alpha`-particle = 2e `:. phi_(E) = (2e)/(epsilon_(0))`
