 Two singly ionized atoms move out of a = slit at point S, as shown in the Figure below, and into a magnetic field 0f 0.10= 0 T. Each has a speed of 1.00 x 106 m/s. The nucleus of the first atom contains one proton and has a mass of 1.67 x 10-27 kg, and the nucleus of the second atom contains two neutrons and has a mass of 3.34 x 1= 0-27 kg. Find their distance of separation when they strike a photographic plate P. 

 

r =3D (mV)/(|q| B)

r1 =3D {(1.67 x 10-27 kg)(1.00 x 106 m/s)}/{(1.60 x 10-19 C)(0.100 T)} =3D 0.104 m

r2 =3D {(3.34 x 10-27 kg)(1.00 x 106 m/s)}/{(1.60 x 10-19 C)(0.100 T)} =3D 0.208 m

d =3D 2 (r2 = 211; r1) =3D 0.207 m
