If the potential across two parallel plates, separated by 3 cm, is 12 volts, what is the electric field strength in volts per meter? e = volts/m

E = 400 V/m

Explanation:

It is given that, for a parallel plates :

Potential difference, V = 12 volts

Separation between the plates, d = 3 cm = 0.03 m

The relation between the electric field and the electric potential is given as :

E = 400 volts/m

So, the strength of the electric field is 400 V/m.                

they should be similar or the same

we need to know the time interval during which the force acts. impulse of force = momentum change
