Finding Electric Force between 2 parallel plates

The electric force acting on the alpha particle placed between two parallel charged plates, with a potential difference of 12.0 V and a distance of 2.00 cm apart, can be calculated using the equation E = V/d. With the given information, the electric force on the alpha particle is equal to 600 N/C. However, the charge of the alpha particle is not provided, making it difficult to calculate the electric force using the equation F = qE.

Homework Statement


An alpha particle is placed between two horizontal parallel charged plates that are 2.00 cm apart. The potential difference between the plates is 12.0 V.

WHAT is the ELECTRIC FORCE acting on the alpha particle?

-Mass of alpha particle: 6.65 x 10^-27 kg

Homework Equations


E = V/d
E = F/q

The Attempt at a Solution


E = V/d
= 12.0 / 0.02
= 600
...im really not sure where to go from here. It seems like the only way to get electric force is by knowing the charge of the particle, but that info isn't given. Is there some way to get around this? :confused:
any help is appreciated, thanks in advanceo:)

An alpha particle consists of two protons and two neutrons...
 

FAQ: Finding Electric Force between 2 parallel plates

1. What is electric force?

Electric force is the force that exists between two electrically charged particles or objects. It can either be attractive or repulsive, depending on the types of charges present.

2. How is electric force calculated?

Electric force can be calculated using Coulomb's Law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

3. What are parallel plates and how do they affect the electric force?

Parallel plates are two flat plates that are placed parallel to each other. They affect the electric force by creating a uniform electric field between them, which causes charged particles to experience a force.

4. How do you find the electric force between two parallel plates?

The electric force between two parallel plates can be found by multiplying the magnitude of the charges on the plates by the electric field strength between them. The electric field strength can be calculated by dividing the voltage difference between the plates by the distance between them.

5. What factors can affect the electric force between two parallel plates?

The electric force between two parallel plates can be affected by the magnitude of the charges on the plates, the distance between the plates, and the presence of any other charged particles in the vicinity that may alter the electric field between the plates.
