Step by Step Solution: Step 1. Determine the electric potential energy gained by the charged particle. Step 2. Use the equation for electric potential energy to relate it to the potential difference and the charge of the particle. \n

U = q V

Step 3. Solve for electric potential energy.\n

U = (- 3 e) (150 V) = - 450 e V

Step 4. Use conservation of energy to find the final kinetic energy of the particle. Since the particle starts from rest, its initial kinetic energy is zero. The total energy at the end is equal to the sum of potential and kinetic energy.\n

K_{f} + U = K_{i}

Step 5. Rearrange the equation to solve for the final kinetic energy of the particle.\n

K_{f} = K_{i} - U

Step 6. Substitute the values of the potential energy and kinetic energy at the beginning.\n

K_{f} = 0 - (- 450 e V) = 450 e V

Final Answer: The final kinetic energy of the particle is

450 eV
