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.

Let vecE and vecB denote the electric and magnetic field in a certain region of space. A proton moving with a velocity along a straight line enters the region and is found to pass through it undeflected. Indicate which of the following statement are consistent with the observation.

If vecE " and " vecB be the electric and magnetic field of E.M. wave then the direction of propogation of E.M. wave is along the direction.

What does the cross product of electric and magnetic field vectors (vecE xx vecB) indicate?

A charged particle moving with a uniform velocity vecv enters a region where uniform electric and magnetic fields vecE and vecB are present. It passes through the region without any change in its velocity. What can we conclude about the (i) relative direction of vecE , vecV and vecB ? (ii) magnetic of vecE and vecB ? or Find the condition under which the charged particle moving with different speeds in the presence of electric and magnetic field vectors can be used to select charged particles of a particular speeds.

Let vecE , vecB and vecC represent the electric field, magnetic field and velocity of an electromagnetic wave respectively. Their directions, at any instant point along the unit vectors given below in order. Which of the following cannot be true?

In electromagnetic wave, if vecE,vecB and vecv are the electric field vector, magnetic field vector and velocity vector of electromagnetic wave, then

Electric field strength vecE = E_0 hati and vecB = B_0 hati exists in a region. A charge is projected with a velocity vecv = v_0 hatj origin, then

An observer A is at rest in gournd frame, observer B is moving with constant another observer C is moving with constant velocity of 1m/s.
