Answer:
1, 2 and 3 are correct.
Explanation:
The force of the attraction is calculated by Coulomb's law as:
Where,
K is the Coulomb's constant having value 9×10⁹ N. m²/C²
are the charges on the dipole and ion respectively.
d is the distance between them.
Since F is inversely proportional to square of distance between them, so statement 1 is true.
F is directly proportional to the charge , so on increasing charge, force of attraction increases. Hence, statement 2 is true.
The greater the magnitude of the dipole means the greater the charge on dipole. Hence, statement 3 is also true.
