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)CN^(-1)C^(-2)`

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
Flux is due to charges enclosed per `epsilon_(0)`
`:.` Total flux `=(-14+78.85-56)nC//epsilon_(0)`
`=8.85xx10^(-9)Cxx(4pi)/(4piepsilon_(0))= 8.85xx10^(-9)xx9xx10^(9)xx4pi`
`1000.4Nm^(2)//Ci.e., 1000 Nm^(2)C^(-1)`

Consider a Gaussian spherical surface covering a dipole of charge q and -q, then

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 . A Gaussian surface encloses two of the four positively charged particles. The particles that contribute to the electric field at a point P on the surface are

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.
