Assume the deformation energy of a diatomic molecule can be expressed by the harmonic potential (shifted in coordinate and energy axes, in general).

The energy of the bond was measured for different interatomic distances:

U(r = 1 Anstrom)= 0.1 Ha; U(r 1.5 Anstrom)0.01; U(r 2.0 Anstrom) 5;

Determine the equilibrium distance and the force constant.

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
