Explanation In order to slow down the protons the acceleration has to be opposite to the direction of motion of the proton. The change in kinetic energy of the proton is the work done. The final velocity of the protons is zero. Thus the work done is equal to the initial kinetic energy of the proton. − F d = 0 − K i Here, F is the force, d is the distance through which the proton is stopped, K i is the initial kinetic energy. Re-write the above equation. E q d = K i Here, E is the electric field, and q is the charge. Re-arrange the above equation. E = K i q d Conclusion: Substitute 3.00 × 10 − 15 J for K i , 1.6 × 10 − 19 C for q , 1
