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`

Electric flux through a closed surface in free space enclosing a charge q is

The electric flux through a chlosed surface area S enclosing charge Q is phi . If the surface area is doubled, then the flux is

In the given figure, there are four point charges placed at the vertices of a square of side, a=1.4 m . If q_(1)=+18 nC,q_(2)=-24 nC,q_(3)+35nC and q_(4)=+16 nC m then find the electric at the centre P of the square Assume the potential to be zero at infinity.

In Fig., the four particles form a square of edge length a = 5.00 cm and have charges q_(1) = +3 nC, q_(2) = -15 nC, q_(3) = +15 nC , and q_(4) = -30 nC . In unit-vector notation, what net electric field do the particles produce at the square's center ?

What is the electric potential at point P, located at the center of the square of charged particles shown in Fig. 24-16a? The distanced is 1.3 m, and the charges are q_(1) = + 12 nC, " "q_(3) = +31 nC , q_(2) = - 24 nC," "q_(4)=+17 nC.

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.

A charge q is enclosed as shown below the electric flux is
