A uniform homogeneous electric field with magnitude of 10v/cm is created inside an airfilled parallel ?

Question

plate capacitor

like this--->

----------------------------------------... <-----8cm

----------------------------------------...

-------------------------A--------------...

----------------------------------------...

------------------------B---------------...

from A to B is 3cm.

where are the positive charges creating the field lines?on the left or right?

ehat is the difference in electric potential?

and what is the capacitance if the distance between the plates is 8cm and the surface area is 10cm squared?this is not dielectric.

Answer 1

Edit: answer: left

Potential difference=V=E*distance=10*8

answer: =80 volts

capacitance=c=e*area/L

e=8.854*10^-12

e = permittivity of space (air is almost identical)

area = 100cm^2=0.01 m^2

100 (cm^2) = 0.01 m^2

L=8/1000=0.008m

c=(8.854*10^-12*0.01)/0.0008

answer:

capacitance=c=1.10675*10^-10 farad
