The electric flux for Gaussian surface A...

The electric flux for Gaussian surface `A` that enclose the charge particles in free space is (given `q_(1)= -14nC,q_(2)= 78.85nC,q_(3)= -56nC)`

A

`10^3 Nm^2 C^(-1)`

B

`10^3 Nm^(-1) m^(-2)`

C

`6.32 xx10^3 Nm^2 C^(-1)`

D

`6.32 xx10^3 CN^(-1) m^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`phi=q_("in")/(epsilon_0)=((-14 + 78.85-56)xx10^(-9))/(8.85 xx10^(-12))=10^3 Nm^2 //C`

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.
