Three point charges are placed as shown ...

Three point charges are placed as shown in the figure. S is a gaussian surface `phi ` is the net flux passing through surface A and E be the electric field at point P on the surface, then

A

Flux `phi " is due to " q_1 " and " q_3` only

B

Flux `phi " is due to " q_1 " and " q_2`

C

Electric field at point P is due to `q_1 " and " q_2` only

D

Flux `phi " is due to " q_3` only

Text Solution

Verified by Experts

The correct Answer is:
B
Electric flux through a closed surface as per Gauss's law depends only on enclosed charges while electric field at any point depends on all the charges.

Gauss's law and Coulomb's law , although expressed in different forms , are equivalent ways of describing the relation between charge and electric field in static conditions . Gauss's law is epsilon_(0) phi = q_(encl) ,when q(encl) is the net charge inside an imaginary closed surface called Gaussian surface. The two equations hold only when the net charge is in vaccum or air . If the charge q_(3) and q_(4) are displaced (always remaining outside the Gaussian surface), then consider the following two statements : A : Electric field at each point on the Gaussian surface will remain same . B : The value of oint vec(E ) .d vec(A) for the Gaussian surface will remain same.
