Let `vecE` and `vecB` denote electric and magnetic fields in a frame S and` vecE'` and `vecB'` in another frame S' moving with respect to S at a velocity `vecv`. Two of the following equations are wrong. Identify them.

Options

A. `E_y^()'=E_y-(vB_z)/(c^2)`
B. `E_y^()'=E_y+vB_z`
C. `B_y^()'=B_y+vE_z`
D. `B_y^()'=B_y+(vE_z)/(c^2)`.

Answer

A, C

Explanation

Check the accuracy of each relation by the method of dimensions.
