Yes, I do use CGS here.

Cross product will be =|E'|*|H'|.

1) [v H] will lie along z-axis. 2)Sure 3)Yes 4)I am not sure, but following a given advice I made calculations above and some adequate result was obtained... 5)When boosting perpendicular to x-y (E-H) plane the only case with some common sense is when x-axis divides angle φ in 2 halves φ/2.

Here is my solution. I also tried another way using scalar product which should be equal to 1 in the new frame. I obtained the same result. If this is right, this solution means the new frame moves with V along x-axis. I am curious if this solution is not unique. We started with a...

Homework Statement In laboratory's frame the angle between vectors E and H is given φ. Find the frame where these vectors will be parallel. Homework Equations The Attempt at a Solution I suppose I should require equal angle between each of the E' and H' and axes in the ''new'' frame. Means...

Should it be like that?

Homework Statement Light (plane wave) reflects from the mirror moving along X-axis with speed V. The wave is orthogonal to the mirror (φ=0°). Write the law for frequency change. Homework Equations I know Lorenz transformation for frequency. The Attempt at a Solution All I do not know is how to...

Oh yes, the question is stated just like there...

Yes, I checked your link above. From their formula m=I*S it follow for 2 electrons m=qwR2 - no 1/c. This result corresponds to the result of 1 electron. But initially I tried to apply the general formula for m=(1/2c)*∫dV [r*j]; this formula was used in class where all tasks were done using CGS...

Homework Statement Electron e, mass m, moves in constant homogeneous magnetic field H. Find time interval for electron's energy to decrease 10 times due to emission. Homework Equations I know for sure from the class that m*a=(e/c)*(v⊥)*H (Lorentz force); intensity -I=dE/dt=-2e4v⊥2H2/(3m2c5)...

Oh yes, I looked up a similar problem with 1 electron. There J=q/T; therefore m=0.5qwR2 What about 1/c? Is it referred to the fact that I used CGS system of units?

Homework Statement Here we have two electrons rotating around z axis with angular speed w in a circle of radius R. They are on the same straight line (have difference in phase π). Find the magnetic moment. Homework Equations Magn. moment m=(1/2c)*∫dV [ r j ] The Attempt at a Solution Current...

Homework Statement ut − 2ux =1/ u; what expressions are constant along the equations's characteristics? Homework Equations 3. The Attempt at a Solution [/B] Am I right? dt=dx/(-2)=du/(-1/u), -2t=x=u2; u=sqrt(x); u=sqrt(-2t) are constant.

Ok, so if we have some g(t) and f(t) in the right part of the eq., then it is inhomogenous, right?

Thank You! I've looked up. Here is something from Wikipedia: So, I stick to my opinion it is linear. But I can't so far decide about it being homogenous... In one Wiki article I read: diff. equation containing non-zero free term in the right part of the equation. This term must be independent...
