1.	Write the atomic symbol for each situation . (a) 7 protons and 8 neutrons . (b) 11 protons and 13 neutrons . (c) Atomic number of 14 with 15 neutrons . (d) 9 protons and a mass number of 10.
Answer» ANSWER: (a) rα ˃ RD ˃ rp (b) rα= rp˂ rd `` (c) rα= rd ˃ rd (d) rα= Explanation: A proton, a deutron and an α- particle having the same kinetic energy are MOVING in circular trajectories in a constant MAGNETIC field. If rp, rd and rα denote RESPECTIVELY the radii of the trajectories of these particles, then (a) rα ˃ rd ˃ rp (b) rα= rp˂ rd `` (c) rα= rd ˃ rd (d) rα= rd = rd

Explanation:

A proton, a deutron and an α- particle having the same kinetic energy are MOVING in circular trajectories in

a constant MAGNETIC field. If rp, rd and rα denote RESPECTIVELY the radii of the trajectories of these particles,

then

(a) rα ˃ rd ˃ rp (b) rα= rp˂ rd `` (c) rα= rd ˃ rd (d) rα= rd = rd
