Acylindrical beam of electric charge flows with uniform velocity u⃗ =10z^ [m/s] the beam's axis is the z^-axis, and it has a radius of r=0.8 [meters] and it has a charge density of rhov=−3r2 [c/m3] calculate the net electric charge flux (the net current) flowing in the +z^-direction through the z=0 plane. give the answer in units of [a]. give three significant figures.

Net electric charge flux is 19.30.

Explanation:

Velocity u =10 z

Charge density ,ρv = - 3r²

r= 0.8 m

The net electric charge given as

u .ds= 10 dA

Now by putting the values

n.e.c=19.30

So the net electric charge flux is 19.30.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
