Calculating Electron Orbit Radius in a Magnetic Field

[kmikias]

Homework Statement

An electron orbits in a 5.76 mT field with an angular momentum of 6.10 x 10-26 kg m2/s. What is the radius of the orbit (in m)?

Homework Equations

F = mv²/r
F= QRB

The Attempt at a Solution

MV²/r = qrb
v = wr
so i plugged and my answer is still wrong .any help please
