http://session.masteringphysics.com/problemAsset/1384904/7/33.P59.jpg

An electron in a cathode-ray tube is accelerated through a potential difference of 10 kV, then passes through the d = 1.9cm-wide region of uniform magnetic field in the figure.

What field strength will deflect the electron by 14 degrees?

One attempt remaining, need the right answer. 5 stars if correct.
