Question
In the figure below, a magnetic field of 0.9 Tesla pointsintothe page. A particle of charge -24 nC and mass 0.8 g isshotinto the field as shown in the figure with a velocity of 0.8km/s.What is the radius of the orbit (in meters)? (The radius is a positive quantity.) Be careful with thepowersof 10. Hint: k=kilo, m=milli, =micro, n=nano and the SIunitsfor B-field, charge, mass, length and time are: tesla (T),coulomb(C), kilogram (kg), meter (m) and second (s),respectively.

Explanation / Answer
=(0.8*10-6 kg * 800 m/s) /(0.9 T * 24 *10-9C) =29629.63 m
