The flux through a surface is given by the scalar product of the field strength and the area
of the surface.
As the rectangular surface is in xy plane the flux corresponding to x and y component of
field will be zero (parallel to the surface) and the flux through the surface is only due to z
component of the field.
Because flux is the dot product of Electric field and area vector. So, parallel to surface is 0.
So,
The z component of the field is varying with x only and directly
proportional to x coordinate. (cx k)
Consider an infinitely thin strip of the surface at a distance x from y axis of thickness dx as
in figure. Field at this strip will have magnitude c*x and will be normal to the surface hence
the flux through this strip will be given by :
Answer:
Option C.
Polarization takes place!
<em><u>Answer:</u></em>
<em><u>Answer:the number of electrons in their outermost shell </u></em>
Final velocity = Vf=0 <span>
Initial velocity = Vi = 9.5m/s
Acceleration = a = -4.6m/s</span>²<span>
Time = t =? </span>
Now use the formula;<span>
Vf=Vi+at
<span>0=9.5 - 4.6m/s</span></span>²t
<span>
-9.5 = -4.6m/s</span>²(t)
9.5/4.6 = t<span>
<span>T= 2.01s</span></span>
Weight = (mass) x (gravity)
Divide each side by (gravity): Mass = (weight) / (gravity) =
(55.54 N) / (9.83 m/s²) =
5.65 kilograms
