Answer:
The correct answer is:
D= [tex]\sqrt{\frac{2.5 h}{N} ][/tex]
Step-by-step explanation:
We have the equation
h = D^2N /2.5 (1)
We have to clear the equation for (1). Multiplying (1) by 2.5
2.5 h = D^2 N (2)
Dividing (2) by N,
[tex]\frac{2.5 h}{N}[/tex] = D^2 (3)
By taking the square root of (3), finally we have
[tex]\sqrt{\frac{2.5 h}{N} ][/tex] = D
