Expert Answer:

Force F acting on the charge q in electric field E is given as,  F = ( qE )
 
Acceleration a experienced by charge,  a = force / mass = (qE)/m  ..........................(1)
 
Vertical displacement due to electric field, y = (1/2) a t2 ..................................(2)
 
where t is time of travel in electric field, t  = distance / speed = x/v .........................(3)
 
Using eqn.(1) and eqn.(3) , we get vertical displacement y from eqn.(2) as
 
y = (1/2) [ (qE ) / m ] ( x / v )2
