Ques. 15 (NUMERICAL)
The region between X = 0 and X Lm is filled with uniform steady magnetic field 2TÂ A particle of
mass 2kg, positive charge 1C and velocity 2(m/s) is travels along x -axis and enters the region of the
magnetic field (neglect gravity). Find the value of L if the particle emerges from the region of magnetic field
with its final velocity at an angle 30° to its initial velocity.
