Physics >> Magnetism >> Moving charge magnetism and force in magnetic field IIT JEE

In a region of space, a uniform electric field 𝐸⃗⃗⃗ , uniform magnetic field 𝐵⃗⃗⃗ and
uniform gravitational field 𝑔⃗ exist in mutually perpendicular direction. A charged particle is
moving with uniform velocity in this region. Once the particle leaves this region and another
where there is only 𝑔⃗ , its speed begins to decrease. How long after leaving the first region
does the velocity of particle reach the minimum value?
