Answer» Answer: The charged particles EXERT electrostatic FORCE on each other. According to the Coulomb's law, the electric force is proportional to the product of the charge, and inversely proportional to the square of separation distance between them. Explanation: Two ions with deficit of 5 electrons on each, i.e. charge on both ions is: q 1
= q
= 5 × e
= 5 × 1.6 × 10 − 19
C
= 8 × 10 − 19
C separation distance between both CHARGES, d
= 20
Angstrom
= 2 × 10 − 9
m Finding the electrostatic force (F) between the charge particles The electrostatic force is CALCULATED as: F
= 1 4 π ϵ o × q 1 × q 2 d 2 F
= 9 × 10 9 × ( 8 × 10 − 19 ) 2 ( 2 × 10 − 9 ) 2 F
= 1.44 × 10 − 9
