Let E and B denote electric and amgnetic fields in a frame S and E1 and B1 in another frame S1 moving with respect to S at a velocity v. Which of the folowing equations are wrong?

(A) B1y = By + vEz/c²

(B) E1y = Ey - vBz/c²

(C) B1y = By + vEz

(D) E1y = Ey + vBz

please explain the answer. This question is from HCV page 230.

ROSHAN MUJEEB · Answer

From Lorentz transformation, Ey&prime;​=&gamma;(Ey​&minus;vBz​) By&prime;​=&gamma;(By​+c2v​Ez​) where&gamma;=1&minus;c2v2​​1​where the symbols have their usual meaning. whencv​<<1&gamma;=1, then the the transformation equations will hold.
