Electric field and magnetic field in Thomson mass spectrograph are applied

SI units of electric field and magnetic field are :

Electric field induced by changing magnetic fields are

Electric field induced by changing magnetic fields are

(A) : In electromagnetic waves electric field and magnetic field lines are perpendicular to each other. (R) : Electric field and magnetic field are self sustaining.

Which of the following statement [s] is ture ? A] Electric field and magnetic field are independent B] Electric field and magnetic field are interrelated C] Electric field and magnetic field may be produced by a stationary charge .

Which of the following statement [s] is ture ? A] Electric field and magnetic field are independent B] Electric field and magnetic field are interrelated C] Electric field and magnetic field may be produced by a stationary charge .

Assertion (A),If electrons travel undefeccted by the electric field E and magnetic field B then the velocity of electrons is given by V=e/b . Reason (R ) : When both electric and magnetic field are applied simultaneously on electron beam. If force due to electric field is equal and opposite to force due to magnetic field then they travel undeflected.
