In summary, the conversation discusses the calculation of the magnitude of electric force acting on an electron moving through an electric field with an acceleration of 6 x 10^3 m/s^2. One person used the formula F = ma and got an incorrect answer, while the other person used the correct formula and got the correct answer. They also discuss discrepancies in the given mass and acceleration values.

Problem 14.
An electron moving through an electric field experiences an acceleration of 6 : 00 * 10^3 m/s^2.
Find the magnitude of the electric force acting on the electron. In units of N.
Note: I used force=mass* acceleration with mass=9.109*10^-19 and the acceleration =6 : 00 * 10^3 m/s^2 and got 5.4654*10^-27 N but it was wrong, what did I do wrong?

[tex]F = ma[/tex]

[tex]F = (9.11x10^-^3^1)(6x10^3)[/tex]

[tex]F = 5.466x10^-^2^7[/tex] N

Where did you get that mass from? What does 6:00 mean? If you used that mass you gave, how did you get that answer?

Answer

this is how it was solved:
F_electric=m_e*a
=(9.109*10^-31)(6.9832*10^6)
=6.361*10^-24N.

Where the heck does 6.9832x10^6 come from?

Mustang:

Your answer is correct if the acceleration is 6 x 10^3.

The other answer is correct if the acceleration is 6.9832 x 10^6.

Pick one.

(I assume your 9.109x10^-19 was just a typo.)

1. What is Electric Force (N)?

Electric force (N) is the measure of the strength of the attraction or repulsion between two charged particles, such as electrons or protons. It is measured in units of Newtons (N).

2. How do you calculate Electric Force?

To calculate Electric Force (N), you can use the equation F = k * (q1 * q2 / r^2), where k is the Coulomb's constant (9 x 10^9 N*m^2/C^2), q1 and q2 are the charges of the two particles, and r is the distance between them.

3. What is the significance of solving Electron Problem 14?

Solving Electron Problem 14 allows us to understand the behavior and interactions of charged particles in an electric field, and it can also be applied to various real-life situations, such as calculating the force between two charged particles in an electronic device.

4. How do you find the direction of Electric Force?

The direction of Electric Force (N) depends on the charges of the particles. If the charges are of the same sign, the force will be repulsive and in the opposite direction to the distance between the particles. If the charges are of opposite signs, the force will be attractive and in the same direction as the distance between the particles.

5. What are some common units for Electric Force?

The most common units for Electric Force (N) are Newtons (N) and Coulombs (C). Other units include Pounds (lbs) and Dynes (dyn). It is important to make sure that all units are consistent when solving for Electric Force.
