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.
