If oint_(s) E.ds = 0 Over a surface, then

STATEMENT -1 : If ointvec(E).bar(ds) over a closed surface is negative,it means the surface encloses a net negative charge. STATEMENT-2 : We may have a Gaussian surface in which three lines enter and five field lines are coming out. STATEMENT-3 : The quantity ointvec(E).bar(ds) is independent of the charge distribution inside the surface.

If for an Amperian loop oint vec(B).vec(dl) = 0 does that mean vec(B) = 0 at every point on the Amperian loop ?

Figure shows five lettered regions in which a uniform magnetic field extends directly either out of the page (as in region a ) or into he page. The field is increasing in magnitude at the same steady rate in all five regions, the regions are identical in area. Also shows are four numbered paths along which oint vec(E). vec(dl) has the magnitudes given below in terms of a quantity mag. Determine whether the magnetic fields in regions b through e are directed into ot out of the page. ? |{:("Path",1,2,3,4),(oint vec(E).vec(dl),mag,2(mag),3(mag),0):}|

The maxwells four equations are written as i. oint vec(E).vec(dS) = (q)/(epsilon_(0)) ii. oint vec(B).vec(dS) = 0 iii. oint vec(E ).vec(dl) = (d)/(dt) oint vec(B).vec(dS) iv. oint vec(B).vec(dl) = mu_(0) epsilon (d)/(dt) oint vec(E).vec(dS) The equations which have sources of vec(E ) and vec(B) are
