A particle with an initial kinetic energy E₀ approaches the origin from x=+ in the presence of a conservative potential. Consider following expressions for the corresponding potential energy V(x) where x is in meters: (i) V(x)=E₀ [1+ - (x / x₀ )^2 ] (ii) V(x)=E₀ [1+1.5 - ((x-5) / x₀ )^2 ] (iii) V(x)=E₀ [1-0.5 - ((x-5) / x₀ )^2 ] (iv) V(x)= E₀ ((x-10) / x₀ )^2 [1-0.5 - ((x-5) / x₀ )^2 ] Here x₀=1 ~m . Select the corre
