A singly charged ion of unknown mass moves in a circle of radius $12.5 \mathrm{~cm}$ in a magnetic field of $1.2 \mathrm{~T}$. The ion. was accelerated through a potential difference of $7.0 \mathrm{kV}$ before it entered the magnetic ficld. What is the mass of the ion?

Step 1
Given: \(Q = 1.6 \times 10^{-19} \, \text{C}\) \(V = 7.0 \times 10^3 \, \text{V}\) Substitute the values: \(v = \sqrt{\frac{2 \times 1.6 \times 10^{-19} \times 7.0 \times 10^3}{m}}\) Show more…

A singly charged ion of unknown mass moves in a circle of radius 12.5 cm in a magnetic field of 1.2 T. The speed of the ion is 9.0x10^4 m/s. What is the mass of the ion?

A singly charged ion of $^{7} \mathrm{Li}$ (an isotope of lithium) has a mass of $1.16 \times 10^{-26} \mathrm{kg}$ . It is accelerated through a potential dif- ference of 220 $\mathrm{V}$ and then enters a magnetic field with magnitude 0.723 T perpendicular to the path of the ion. What is the radius of the ion's path in the magnetic field?
$\bullet$ Singly ionized (onne electron removed) atoms are accelerated and then passed through a velocity selector consisting of perpendicular electric and magnetic fields. The electric field is 155 $\mathrm{V} / \mathrm{m}$ and the magnetic field is 0.0315 $\mathrm{T}$ . The ions next enter a uniform magnetic field of magnitude 0.0175 $\mathrm{T}$ that is oriented perpendicular to their velocity. (a) How fast are the ions moving when they emerge from the velocity selector? (b) If the radius of the path of the ions in the second magnetic field is $17.5 \mathrm{cm},$ what is their mass?
