## Homework Statement

An ion is accelerated through potential diff. of 250 V, directly perpendicular to mag. field.

Find radius of the path of the ion in the field.

Given:

mass (m)=2.5 x 10^-26

charge(q)= 1.6 x 10^-19

Volts= 250 V

Mag. Field (B) = 0.50 T

## Homework Equations

radius= (mass x VELOCITY)/ (charge x B)

## The Attempt at a Solution

I know the answer is 1.77 cm for the radius, but i need to prove how, but i can't seem to find an equation or reason to use Volts to get Velocity in the equation.
