Deriving the trajectory of the particle

In summary, the problem involves a particle with mass m and charge q being released at the origin in the presence of a uniform electric field E and a uniform magnetic field B. The only acting force on the particle is the Lorentz force. The goal is to derive the trajectory of the particle for t>=0. Hints given by the conversation include considering Newton's 3rd law and the sum of forces being equal to 0.

Homework Statement


There is a uniform electric field E, and a uniform magnetic field B in space. A particle of mass m, and charge q, at the origin is released from rest at t=0. The only acting force on the body is the Lorentz force. Derive the trajectory of the particle for t>=0.


Homework Equations


Lorentz force: F=q(E+v*B)

Hint: sum of forces equals what?

thanks

forces? it says the only force is Lorentz one...

hey I am totally newbie to EM. :P

OK, let me rephrase the question: which of Newtons laws is relevant here?
 
  • #5
3rd law, and the sum is 0
 

1. What is the process of deriving the trajectory of a particle?

The process of deriving the trajectory of a particle involves using equations and laws of motion to calculate the position, velocity, and acceleration of the particle over time. This information can then be used to plot the path or trajectory of the particle.

2. What are the key variables needed to derive the trajectory of a particle?

The key variables needed to derive the trajectory of a particle are the initial position, initial velocity, and any external forces acting on the particle. Other factors, such as mass and air resistance, may also need to be considered depending on the specific situation.

3. How accurate is the derived trajectory of a particle?

The accuracy of the derived trajectory of a particle depends on the accuracy of the initial conditions and the assumptions made in the calculations. In ideal situations, the derived trajectory can be very accurate, but in real-world scenarios, there may be slight discrepancies due to factors such as air resistance and external forces.

4. Can the trajectory of a particle be derived for all types of motion?

Yes, the trajectory of a particle can be derived for all types of motion, including linear, projectile, circular, and even complex motions. The equations and laws of motion used may vary depending on the type of motion, but the process of deriving the trajectory remains the same.

5. Can the trajectory of a particle be predicted for future time intervals?

Yes, if the initial conditions and external forces remain constant, the trajectory of a particle can be predicted for future time intervals using the derived equations. However, if there are changes in the initial conditions or forces, the trajectory may need to be recalculated using the updated information.
