Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Physics Work Power and Energy Potential Energy
Potential energy as a function of r is given by \(U=\frac{A}{r^{10}}-\frac{B}{r^5}\), where r is the interatomic distance, A and B are positive constants. The equilibrium distance between the two atoms will be:
1
\(\left(\frac{A}{B}\right)^{\frac{1}{5}}\)
2
\(\left(\frac{B}{A}\right)^{\frac{1}{5}}\)
3
\(\left(\frac{2 A}{B}\right)^{\frac{1}{5}}\)
4
\(\left(\frac{B}{2 A}\right)^{\frac{1}{5}}\)
5
