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 relative direction of vecE , vecv and vecB?

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.
