    The force acting on a particle of mass m moving along the x-axis is given by F(x) = Ax2 - Bx. Which one of the following is the potential energy of the particle?

    2Ax - B

    Incorrect Answer

    -x2/6 (2Ax - 3B)

    Correct Answer

    Ax3 - Bx2

    Incorrect Answer

    Zero

    Incorrect Answer
    Explanation:

    Potential Energy = - ∫ F(x) dx

    U(x) = - ∫ (Ax2 - Bx) dx

    U(x) = - Ax3/3 + Bx2/2

    U(x) = -x2/6 (2Ax - 3B)
