A uniform electric field E is present horizontally along the paper throughout the region and uniform magnetic field B0 is present horizontally (perpendicular to plane of paper in inward direction) right to the line AB. A charge particle having charge q and mass m is projected vertically upward and it crosses the line AB after time t0. Find the speed of projection if particle moves with constant velocity after t0 . (Given qE = mg)
  • a)
     gt0
  • b)
    2gt0
  • c)
  • d)
     Particle can’t move with constant velocity after crossing AB
Correct answer is option 'B'. Can you explain this answer?

A uniform electric field E is present horizontally along the paper thr...
Let velocity of particle at ‘P’ is ‘v’ making an angle ‘θ’ with x-axis
(P is the point where particle is crossing AB line)
⇒As after reaching point ‘P’, velocity of particle remain constant, so net force acting on particle will be zero at ‘P’
Now, horizontal velocity at point ‘P’ is due to Electric force qE
