Two 3.00 cm × 3.00 cm plates that form a parallel-plate capacitor are charged to ± 0.708 nc . part a what is the electric field strength inside the capacitor if the spacing between the plates is 1.30 mm ?

Explanation:

The electric field strength between the plates of a parallel plate capacitor is given by

where

is the surface charge density

is the vacuum permittivity

Here we have

is the area of the plates

is the charge on each plate

So the surface charge density is

And now we can find the electric field strength

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
