Q: A particle of potential energy shown in graph is moving towards right. The initial kinetic energy of particle is 21 J at x = 0

Mark the correct option (s)

(a) The particle accelerates for 0 ≤ x < 1 m

(b) At x = 1 m, the particle has minimum KE energy

(c) The kinetic energy is 41 J at x = 3 m

(d) The particle is trapped within 0 < x ≤ 4

Ans: (b) , (c)

Sol: As we know that Total Mechanical Energy = Potential Energy + Kinetic Energy ; Which is constant

Hence Where Potential Energy is maximum , Kinetic Energy is minimum and Vice Versa

At x = 1 , Potential Energy is maximum , Hence Kinetic Energy is minimum at x = 1
