My mistake, I did use the diameter/ 2 in my calculations ( just translated it incorrectly) so I still had the same calculation. Is there something else I am missing?

[b]1. [b]1. An air-core solenoid with 57 turns is 4.96 cm long and has a diameter of 1.46 cm. The permitivity of free space is 4×10−7 T· m/A. How much energy is stored in its magnetic field when it carries a current of 0.634 A ? Answer in units of μJ. [b]2. B = mu-o (I) (N)/ L...

Substitution worked wonderfully! Thanks again!

So would I be able to solve equations 3 and 4 somehow to find mass and velocity? Those are my two unknowns. I need velocity to solve for mass. Is there another relationship I am missing to help me solve for velocity?

[b]1. A 1.56024 μC charged particle with a kinetic energy of 0.115905 J is placed in a uniform magnetic field of magnitude 0.150267 T. If the particle moves in a circular path of radius 3.13685 m, find its mass. Answer in units of kg. Homework Equations Fe= Fm Fe= qE KE=mv^2/2 Fm=...

Thank you! I just needed that missing piece!

[b]1. A singly charged positive ion has a mass = 1.08e-26 kg After being accelerated through a potential difference of 240 V the ion enters a magnetic field of 0.595 T in a direction perpendicular to the field. The charge on the ion is 1.602 e-19 C. Find the radius of the ion's path in the...
