Answer:
correct order of work done is given as
2 > 3 > 4 > 1
Explanation:
When positive charge is dragged opposite to electric field then in that case work done is positive while if negative charge is dragged opposite to electric field then the work done is negative
So here we will have
positive work for charge 2, 3 and 4 while for negative charge particle 1 the work done is negative
now here we also know that work done is product of force and displacement
so here work depends on displacement of charge particle
maximum displacement is force particle 2
minimum is for particle 4
so correct order of work done is given as
2 > 3 > 4 > 1
