Question
A positive ion moves at a velocity of 2.4x10^5 ms in a circular path of radius 1.8m when a magnetic field of 0.315 T is applied. Find the mass of the ion. Assume a single charge.

A single positive charge = 1.6 * 10^-19 C
qvB = mv ² / r
Rearrange to find m:
m = qrB / v
m = (1.6 * 10^-19 C)(1.8 m)(0.315 T) / (2.4 * 10^5 m/s)
m = _______ kg
