Explanation:
Given that,
Force![Rendered by QuickLaTeX.com F=-\alpha x^2 i](https://documen.tv/wp-content/ql-cache/quicklatex.com-722b9b7b21acc3d6cf7528d4e71ceffe_l3.png)
We need to calculate the potential energy
Using formula of work done
Put the value of F
On integration
U = 0, x = 0 so C = 0
Put the value of c and α in equation (I)
Hence, The potential energy is![Rendered by QuickLaTeX.com -4x^3](https://documen.tv/wp-content/ql-cache/quicklatex.com-580a79811783505f76ea1ba54e50d1dc_l3.png)
