➷ 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
