In fact I know the answers of this problem, but I have a question.
Here's the question.
A charge +q moving with constant velocity v enters into a uniform magnetic field region as shown. The magnetic flux density is B.
a) What is the direction of the force F experienced by q?
b) What is the work done by F?
c) What kind of motion it is performing?
d) Express the radius of curvature r of the change in terms of B, v, m and q. Where m is the mass of the charge.
ans:
a) Direction of force is always perpendicular to the direction of q. The point charge will go upward.
From the part (d), I know it is performing circular motion and that the work done by F is 0 J!
d) r = mv/(Bq)
Why it is performing circular motion? Can't it be an elliptical motion?
