Direction and magnitude of magnetic force on electron + radius of path

0 pts pending
a. Find the direction and magnitude of the magnetic force on an electron presently traveling to the right at 7.5 × 106 m/s, in a uniform 3.3-T B-field directed into the page, as shown here. (Ignore relativistic effects and gravity.) Also, draw and LABEL the FB vector on the electron at the moment shown here:
The electron will travel in a circular path as long as it remains inside a uniform B-field.
b. Will its circular motion be clockwise or counter-clockwise (as viewed in the diagram above)? Draw the electron’s path on the diagram above, and put arrowheads along the path to indicate direction of motion.
c. Find the radius of its path, given the values in part (a). Show your work.
