# Let and denote electric and magnetic fields in a frame S. and in another frame S’ moving with respect to S at a velocity Two of the following equations are wrong. Identify them.

A.

B.

C.

D.

Answer :

Formula used:

Electric force is given by

Where F is electric force

q is electric charge =

E is electric field

Magnetic force is given by

Where F is magnetic force

q is electric charge =

v is velocity

B is magnetic force

From the above formulas and

From the dimensional analysis we can write equations as

i.

ii.

So only options A and D are correct.
