Question

4 (a) What is the magnitude of the electrostatic force between a
singly charged sodium ion (Na*, of charge +e) and an adjacent
singly charged chlorine ion (C1. of charge -e) in a salt crystal if
their separation is 2.82 x 10-10m? (b) What is the force magni-
tude il radiation removes another electron from the sodium ion?​

Answer 1

Resposta:

a) 2,9.10^(-9) N

b)5,8.10^(-9) N

Explicação:

a) F = (k.q1.q2)/d^2

F = (9.10^(9).1,6.10^(-19).1,6.10^(-19))/(2.82.10^-10)^2 = 2,9.10^(-9) N

b) F=(9.10^(9).3,2.10^(-19).1,6.10^(-19))/(2.82.10^-10)^2 = 5,8.10^(-9) N
