wht is divergins of a vector field.......................

[QUOTE]wht is divergins of a vector field....................... [/QUOTE]

[B]"amount of certain flux per unit volume of a vector field is called divergence of vector field"
now there are two conditions of divergence
1-it must b zero
2-it must b non-zero(it may b +ve or -ve)

[COLOR="DarkOrange"]*[/COLOR]when incoming and outgoing of electric lines of forces is same divergence will b zero n density ll be constant
i.e flow of water from pipe

[COLOR="darkorange"]*[/COLOR]when outgoing increases as compare to incoming it gives +ve divergence.in this case density will decrease....(bcz it may have some fluid or water that was already exsist in pipe thats y outgoing increase)

[COLOR="darkorange"]*[/COLOR]when outgoing decreases as compare to incoming it gives -ve divergence.in this case density will increase
(bcz may b some fluid or water remained in pipe thats y outgoing decrease)

if u ve any problem in it ....ask it freely.............
