a block of mass m containing a negative charge -q is placed on frictionless surface and is connected with a wall through an unstretched spring of spring constant k. if horizontal electic field is applied parallel to spring is switched ON , then find maximum compression in spring?

The answer would be: 
 
from work energy theorem,
Electric Force x y = 0.5ky^2
 
Force = q*E
Hence,
y = 2qE/k meter.
This would be the maximum xompression in spring.
where E is the constant electric field.
