Question

A singly charged positive ion has a mass of 3.20*10^_26kg . after being accelerated from rest through a p.d of 833v,the ion enter magnetic field of 0.920T a long a direction perpendicular to the direction of the field.cal.the radius of the path.

Answer 1

a. compute the KE of the first pd.
b. calculte the force of the magnetic field on the ion
c. that force has to equal the centripetal force, mv^2/r, so calculate r, knowing velocity and mass.

Answer 2
