A positive charge and a negative charge are initially at rest. If same electric field is applied on them.

Given data: Both positive and negative charge both are rest 

Concept Used: Electric field 

Detailed Solution:

As we know the concept of electric field, positive charge moves in the direction of electric field and negative charge moves opposite to the direction of electric field. 

Thus positive charge has accelerated motion in the direction of the field and negative charge has also accelerated motion but in a direction opposite to that of the field
