A particle with charge q and momentum p, initially moving along the x-axis, enters a region where a uniform magnetic field* B=(B

VMariaS [17]

Answer:

Magnitude of momentum = q × B0 × [d^2 + 2L^2] / 2d.

Explanation:

So, from the question, we are given that the charge = q, the momentum = p.

=> From the question We are also given that, "initially, there is movement along the x-axis which then enters a region where a uniform magnetic field* B = (B0)(k) which then extends over a width x = L, the distance = d in the +y direction as it traverses the field."

Momentum,P = mass × Velocity, v -----(1).

We know that for a free particle the magnetic field is equal to the centrepetal force. Thus, we have the magnetic field = mass,.m × (velocity,v)^2 / radius, r.

Radius,r = P × v / B0 -----------------------------(2).

Centrepetal force = q × B0 × v. ----------(3).

(If X = L and distance = d)Therefore, the radius after solving binomially, radius = (d^2 + 2 L^2) / 2d.

Equating Equation (2) and (3) gives;

P = B0 × q × r.

Hence, the Magnitude of momentum = q × B0 × [d^2 + 2L^2] / 2d.

At a particular moment in time and space, we measure an electromagnetic wave's electric and magnetic fields. We find the electri

kolbaska11 [484]

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

∴ $E$ × $B$ $= k$

Where $E =$ direction of electric field, $B =$ direction of magnetic field, $k =$ 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.
