A sphere of radius R and charge Q is placed inside an imaginary sphere of radius `2R` whose centre coincides with the given sphere. The flux related to imaginary sphere is:

A

`Q/in_(0)`

B

`Q/(2in_(0))`

C

`(4Q)/in_(0)`

D

`(2Q)/in_(0)`

Text Solution

Verified by Experts

The correct Answer is:
A
From flux `=int vec(E).vec(ds)=(Eq_("enclosed"))/in_(0) :.` flux `=Q/in_(0)`
