Answer:
The magnitude of the Force is and the direction is South
Explanation:
From the question we are told that
The magnetic field point due west and since East point toward the positive x -axis then this magnetic field would be mathematically represented as
Now from the question we are told that the kinetic energy is
Now this kinetic energy can be mathematically represented as
Where m is the mass of proton which has a general value of
Now making the subject of the formula
Substituting values we have
Now from the question we are told that proton is moving upward which is in the positive z direction so the velocity of the proton would be in the positive
So the velocity would be
Now the magnetic Force can be mathematically represented as
Where q is the charge on the proton which has a general value of
Now substituting the value
Now according to Fleming's left hand rule the direction of the magnetic force is south toward the negative Y - direction
So the force can be denoted as
Answer:
The direction of propagation is west.
Explanation:
We know that electromagnetic waves (EM-waves) are transverse in nature. EM-waves containing electric field and magnetic field both are perpendicular to the each other ( E ⊥ B ).
Transverse waves : the direction of propagation is perpendicular to the direction of amplitude which we call transverse waves. eg : light waves, water waves, gravitational waves etc.
Here, in our case the direction of electric field is pointing upward to the plan of the screen and the direction of magnetic field is pointing north
∴ ×
Where direction of electric field,
direction of magnetic field,
direction of propagation at particular instant.
Above equation follows right hand rule. put your finger toward you (out of the screen) then curl to the north side then the thumb will give you the direction of the wave propagation ( west side )
In our case west direction is the direction of wave propagation.
