Answer:
Part a)

Direction of force is along the motion of charge
Part b)

direction of electric field is along the direction of motion
Explanation:
Part a)
As we know that the change in electric potential energy is equal to the work done by electric field


now from the equation of work done we know that



Direction of force is along the motion of charge
Part b)
As we know the relation between electrostatic force and electric field given as



direction of electric field is along the direction of motion
