Refer to the arrangement of charges in shown figure and a Gaussian surface of radius R with Q at the centre. Then:

A

total flux through the surface of the sphere is `(-Q)/(4piepsilon_(0)R^(2))`

B

field on the surface of the sphere is

C

flux through the surface of sphere due to 5Q is zero.

D

field on the surface of sphere due to -2Q is same everywhere.

Text Solution

Verified by Experts

The correct Answer is:
A, C
Charge enlosed by sphere,
`=-2Q +Q`
`=-Q`
`therefore` flux associated with flux,
`phi = -Q/epsilon_(0)` (`therefore` According to Gauss.s law)
As SQ is outside, it doesn.t play any role in flux.

An infinite, uniformly charged sheet with surface charge density sigma cuts through a spherical Gaussian surface of radius R at a distance X from its center, as shown in the figure. The electric flux Phi through the Gaussian surface is .

Assertion:- In a given situation of arrangement of charges, an extra charge is placed outside the Gaussion surface. In the Gauss Theroem ointvecEdvecs=(Q_(in))/(epsilon_(0)).Q_(in) remains unchanged whereas electric field vecE at the site of the element is changed. Reason:- Electric field vecE at any point on the Gaussian surface is due to inside charge only.
