Question

A charged particle moving with constant velocity passes through a region of space without any change in its velocity. If E and B represent electric and magnetic fields in that region respectively,what is the E and B in this space ?

• A. $E=0$ and $B=0$
• B. $E=0$ and $B\ne 0$
• C. $E\ne 0$ and $B=0$
• D. $E\ne 0$ and $B\ne 0$

Answer 1

The correct option is D $E\ne 0$ and $B\ne 0$

We know that any moving charged particle will both have the electric and magnetic field.

So when a charged particle moving with constant velocity passes through a region of space without any change in its velocity, it both have magnetic and electric field, $E\ne 0andB\ne 0$
