(a) Find the magnitude of the electric force between a Na+ ion and a Cl- ion separated by 0.50 nm. (b) Would the answer change if the sodium ion were replaced by Li+ and the chloride ion by Br-? Explain. 

A uniform electric field of magnitude 640 N/C exists between two parallel plates that are 4.00 cm apart. A proton is released from the positive plate at the same instant that an electron is released from the negative plate.

(a) Determine the distance from the positive plate at which the two pass each other. (Ignore the electrical attraction between the proton and electron).

(b) Repeat part (a) for a sodium ion (Na+) and a chlorine ion (Cl-).

A uniform electric field of magnitude 640 N/C exists between two parallel plates that are 4.00 cm apart. A proton is released from rest at the positive plate at the same instant an electron is released from rest at the negative plate. (a) Determine the distance from the positive plate at which the two pass each other. Ignore the electrical attraction between the proton and electron. (b) What if? Repeat part (a) for sodium ion (Na⁺) and a chloride iron (Cl^-). 

The magnitude of the electrostatic force between two identical ionsthat are separated by a distance of 5.0 multiplied by 10-10 m is1.47 10-8 N.
(a) What is the charge of each ion?
1Your answer is incorrect. C

(b) How many electrons are "missing" from each ion (thus giving theion its charge imbalance)?
2Your answer is incorrect. electrons
