In an inertial reference frame K there is only a uniform electric field E = 8 kV/m in strength. Find the modulus and direction (a) of the vector E', (b) of the vector B' in the inertial reference frame K' moving with a constant velocity v relative to the frame K at an angle α = 45° to the vector E. The velocity of the frame K' is equal to a β = 0.60 fraction of the velocity of light. |
