Question

A charged particle enters a region of uniform 3.25 T magnetic field into the page and is at point P as shown. It moves along a circular path with a radius 2 m and constant speed of 10 m/s. Find the charge to mass ratio, |q|/m of the particle in units of C/kg.

What is the type of charge of the particle?

A charged particle enters a region of uniform 3.25 T magnetic field into the page and is at point P as shown. It moves along a circular path with a radius 2 m and constant speed of 10 m/s. Find the charge to mass ratio, |q|/m of the particle in units of C/kg. What is the type of charge of the particle?

Explanation / Answer

Apply r = mv/qB

q/m = v/Br

q/m = (10)/(3.25)(2)

q/m = 1.54 C/kg

The charge is positive (by the right hand rule)
