Q- A particle moves in a region having a uniform magnetic field and parallel electric field.At some instant the velocity of a particle is perpendicular to the field direction.The path of a particle will be?
a) straight line
b)circle
c) helix with uniform pitch
d) helix with non uniform pitch EXPLAI?N ALS?O??
At the instant of starting, the path is a circle.The electric field causes the particle to accelerate perpendicular to the plane of the circle caused by the magnetic field. Therefore the path is a helix
mv2/r = evB, r= mv/eB = Et/eB
In addition,because v increases with time, the helix has the shape of a stretched out, spring whose radius increases continuously from turn to turn. Therefore, the correct answer is option 'd'
