Is this how to attempt this problem on electric field strength

In summary, the conversation discusses the calculation of electric field strength between two parallel plates at different voltages and with a separation of 35cm. The equation used is E = v/d and the resulting value is 420x10^3 N/C. The topic later shifts to the force experienced by a proton between the plates, which can be calculated using the equation F = qE. The direction of the force should also be taken into consideration.

Hello Kieran, :welcome:

In one word: yes !

(However, since you only get two digits from the voltage, perhaps 420 ##\times 10^3\ ##N/C is a bit cleaner. But by all means: do further calculations with the number you found.)

Okay, great! Thank you

The question later goes on to ask what force is experienced by the proton and i really don't know where to start on this one, could you try shed some light on this for me? Thanks

For that you need a relevant equation, something like Force = Electric field strength * charge, or ## \vec F = q \vec E##. You have the two factors on the right, so: no problemo. But check the direction !
 

Related to Is this how to attempt this problem on electric field strength

1. What is electric field strength?

Electric field strength is a measure of the force exerted on a charged particle at a given point in space. It is represented by the symbol E and is measured in newtons per coulomb (N/C).

2. How do you calculate electric field strength?

Electric field strength can be calculated using the formula E = F/q, where E is the electric field strength, F is the force exerted on the charged particle, and q is the charge of the particle.

3. What are the units for electric field strength?

Electric field strength is measured in newtons per coulomb (N/C). This unit is equivalent to volts per meter (V/m).

4. How does distance affect electric field strength?

The electric field strength is inversely proportional to the square of the distance from the source of the electric field. This means that as the distance increases, the electric field strength decreases.

5. What factors affect electric field strength?

The factors that affect electric field strength include the magnitude of the charge creating the field, the distance from the source of the field, and the medium through which the field is passing. Other factors such as the presence of other charged particles or objects can also affect the electric field strength.
