Answer:
C and D are correct
Explanation:
An electric dipole moment for pair of equal and opposite charges is defines the magnitude of charge times the distance between them and the direction is always towards the positive charge. According to the definition only points C and D are correct.
C) No net force acts on the electric dipole.
D) There are no electric forces exerted on each pole of the dipole.

Answer:
Part a)
Work done is given as
W = -121.5 J
Part b)
Potential energy of the system is given as
Explanation:
As we know that work done by variable force is given as
here we know that
so we have
so we have
here we displace it from x = 2 to x = 5
so we will have
Part b)
As we know that change in Potential energy = work done
