  46. A disk of radius a/4 having a uniformly distributed charge 6C is placed in the x-y plane with its centre at (-a/2 0 0) .A rod of length a carrying a uniformly distributed charge 8C is placed on the x-axis from x=a/4 to x=5a/4.Two point charges -7C and 3C are placed at (a/4 -a/4 0) and (-3a/4 3a/4 0) respectively. Consider a cubical surface formed by six surfaces x= +- a/2 y=+-a/2 z=+-a/2.The electric flux through this cubical surface is?

  48. Why is Gauss' Law not valid in case of dipoles? I mean to say that Electric field is present around a dipole.
    8 years ago by Shivam Agarwal
    Ans 1 ->
    if you'll apply gauss thm. to entire dipole then you'll put it inside a closed / gaussian surface and then net charge will become zero due to obvious reasons, and Gauss theorem says flux = q/ epsilon (not). since net charge is now zero therefore you won't be getting any net flux therefore we use conventional ways to find it's electric field and not the gauss thm.
    8 years ago by ANURAG KAUSHIK
    Ans 2 ->
    well try to understand gauss law it states the surface area integral is flux = q inside/e0 .here q=0 flux enclosed =0 ie every field line that start with =ve charge end in -ve charge, that surly doesnot imply E=0

  58. what is gauss theorem
    8 years ago by RAMU SHARMA
    Ans 1 ->

  63.  
  64. If we keep the electric field constant and on increasing the area (say A1 to A2 where A2 is greater then A1) then it implies that phi1=EA1 is smaller than phi2=EA2. but as electric flux is the measure of electric field strength then how on increasing only the area can increase the strengh of electric field?(whenE is not changing)
    9 years ago by sudeep khare
    Ans 1 ->
    flux also depends on area as phi = EA

  66. electric flux as defined - just the no. of electric field lines passing through the given area . Then why does it has unit as V-m ? Why it is not UNITLESS ?
    9 years ago by Mohit Kuri
    Ans 1 ->
    Flux tells us about the...strength of electric field..electric field lines are jus imaginary you can't really calculate their no. ..its jus the strength
