561 - Physics Questions Answers

In a region of space, a uniform electric field 𝐸⃗⃗⃗ , uniform magnetic field 𝐡⃗⃗⃗ 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?
