page 09 11. An alpha particle is accelerated in an electric field between metal plates P and Q. − + alpha particle Q P The charge on the alpha particle is 3·2 × 10-19 C. The kinetic energy gained by the alpha particle while travelling from plate P to plate Q is 8·0 × 10-16 J. The potential difference across plates P and Q is A 2·6 × 10-34 V B 2·0 × 10-4 V C 4·0 × 10-4 V D 2·5 × 103 V E 5·0 × 103 V. [Turn over
