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.

false

explanation:

boats, things on boats luggage are way more heavy then water.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
