JEE MainPhysicsWork Power and EnergyMCQ+4 / −1
Given below is the plot of a potential energy function U(x) for a system, in which a particle is in one dimensional motion, while a conservative force F(x) acts on it. Suppose that Emech = 8 J, the incorrect statement for this system is : JEE Main 2021 (Online) 27th July Evening Shift Physics - Work Power & Energy Question 79 English [ where K.E. = kinetic energy ]
  1. A
    at x > x4 K.E. is constant throughout the region.
  2. B
    at x < x1, K.E. is smallest and the particle is moving at the slowest speed.
  3. C
    at x = x2, K.E. is greatest and the particle is moving at the fastest speed.
  4. D
    at x = x3, K.E. = 4 J.
