Rank the work done on the charged particles from highest to lowest

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
