a charged particle moves in a gravity free space without change in velocity.which of the following is are possible and why?
a.E=0,B=0 b.E=0,B not equal to 0 c.E not equal to zero and B=0 d.E and B BOTH not equal to zero
The following situations are possible:
E = 0, B = 0
Particle move with constant velocity in any direction.
So B = 0, E = 0
E = 0, B is not equal to 0
Particle move in a circle with constant speed.
Magnetic force provides the centripetal force that causes particle is move in a circle.
E and B are not equal to zero
If qE = qvB and magnetic and Electric force are in opposite direction. In this case particle also move with uniform speed.
E = 0, B = 0

So B = 0, E = 0
E = 0, B is not equal to 0
