Professor PC Thomas Classes · Answer

(c) : Force constant $(k)=2 	imes 10^{6} \mathrm{~N} / \mathrm{m}$;\ displacement $(x)=0.01 \mathrm{~m}$ and total mechanical energy $=160 \mathrm{~J}$.\ Potential energy $=\frac{1}{2} k x^{2}=\frac{1}{2} 	imes\left(2 	imes 10^{6}ight)(0.01)^{2}=100 \mathrm{~J}$\
