An air-filled capacitor consists of two parallel plates, each with an area of 7.60 cm2, separated by a distance of 1.60 mm. If a 15.0 V potential difference is applied to these plates, calculate the following.

(a) the electric field between the plates
kV/m

(b) the capacitance
pF

(c) the charge on each plate
pC

Given Information:

Area of separation = A = 7.60 cm² = 0.000760 m²

distance = d = 1.60 mm = 0.0016 m

Potential difference = V = 15.0 V

Required Information:

(a) Electric field = E = ?

(b) Capacitance = C = ?

(b) Charge = Q = ?

(a) Electric field = 9.375 kV/m

(b) Capacitance = 4.205 pF

(b) Charge = 63.08 pC

Explanation:

(a) The electric field between the plates  kV/m

We know that electric field is given by

E = V/d

E = 15.0/0.0016

E = 9.375x10³ V/m

or

E = 9.375 kV/m

(b) the capacitance  pF

The capacitance is given by

C = ε*A/d

where ε = 8.854×10⁻¹² F/m

C = 8.854×10⁻¹²*0.000760/0.0016

C = 4.205x10⁻¹² F

or

C = 4.205 pF

(c) the charge on each plate  pC

The charge on each plate is given by

Q = ε*E*A

Q = 8.854×10⁻¹²*9.375x10³*0.000760

Q = 63.08×10⁻¹² C

or

Q = 63.08 pC

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
