The force F(x)\mathrm{F}(x) acting on a body of mass m changes with position xx (in meter) as shown. It is given that the potential energy U(x)=0\mathrm{U}(x)=0 at x=0x=0 Choose correct option(s). The force F(x) acting on a body of mass m changes with position x (in meter) as shown. It is given that the potential

Options

  1. AU(x)=0\mathrm{U}(x)=0 at x=0,x=3x=0, x=3 and x=6x=6
  2. BU(x)=2x2−12x\mathrm{U}(x)=2 x^2-12 x for 2≤x≤42 \leq x \leq 4
  3. CU(x)=−x2+12x−40\mathrm{U}(x)=-x^2+12 x-40 for 4≤x≤64 \leq x \leq 6
  4. DAt x=3,U(x)=−10 Jx=3, \mathrm{U}(x)=-10 \mathrm{~J}

Correct answer

D. At x=3,U(x)=−10 Jx=3, \mathrm{U}(x)=-10 \mathrm{~J}
