Charges Q1 and Q2 lie inside and outside...

Charges `Q_1 and Q_2` lie inside and outside, respectively, of a closed surface S. Let E be the field at any point on S and `phi` be the flux of E over S.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Electric flux depends on the total charge enclosed by the closed surface S. Hence flux is related with charge `Q_(1)`. Electric field at a point is the vector sum of the all electric field intensities due to all charges.

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.
