An Alpha Particle of Charge +2e and Mass 41 $\alpha$ /r_O = 1/1

question 99

Multiple Choice

An alpha particle of charge +2e and mass 41.66 × 10^-27) kg, and an ¹⁶O nucleus of charge +8e and mass 161.66 × 10^-27) kg have been accelerated from rest through the same electric potential. They are then injected into a uniform magnetic field B, where both move at right angles to the field. The ratio of the radius of the path of the alpha particle to the radius of the path of the nucleus ¹⁶O is

• A) r_\(\alpha\)/r_O = 1/1.
• B) r_\(\alpha\)/r_O = 1/4.
• C) r_\(\alpha\)/r_O = 1/8.
• D) r_\(\alpha\)/r_O = 1/2.
• E) None of these is correct.
