Answer:
আমরা জানি,
[tex]E = \frac{1}{2} k {x}^{2} \\ \therefore \: E \: \propto \: {x}^{2} \\ [/tex]
এখন,
আদি সরণ [tex] x_1[/tex] = x
পরিবর্তিত সরণ [tex] x_2 [/tex] = 2x
১ম অবস্থায় কাজ [tex] E_1 [/tex]
২য় অবস্থায় কাজ [tex]E_2 [/tex]
[tex] \: \: \: \: \: \: \: \: \sf \frac{E_2}{E_1} = \frac{x_2 ^{2} }{x_1 ^{2} } \\ \sf \implies \: \frac{E_2}{E_1} = \frac{ {(2x)}^{2} }{ {x}^{2} } = \frac{4 {x}^{2} }{ {x}^{2} } = 4 \\ \therefore \: E_2 = 4E_1 \\ \\ \Delta \: E = E_2 - E_1 = 4E_2 - E_1 \\ \: \: \: \: \: \: \: = 3E_1 \\ \: \: \: \: \: \: \: = \frac{3E_1}{E_1} \times 100 \: \% \: \\ \: \: \: \: \: \: \: \: = 300\% \\ [/tex]
