➷ E = k/d^2

k is the constant

Substitute the values given in:

29.388 = k/2.1^2

Multiply both sides by 2.1^2 to get the constant

k = 129.60108

The equation that models this is:

E = 129.60108/d^2

Substitute the values in:

4.614 = 129.60108/d^2

Divide both sides by 4.614 to get d^2

d^2 = 28.0886606

d = 5.29987364

This can be rounded to 5.3
