Hi, may I conclude this: question says that the direction vector V intersect the sphere at point B, does it mean that that vector V intersect the sphere at ONLY one point and therefore, vector V is a tangent to the sphere?

as you see in the image V is reflected by the sphere (like a mirror) and passes the C. So B is a very specific point. V as a tangent is a very unique situation of the question which makes the angle of VBC=180 and is not always true.

This is definitely not the answer.
I couldn't bear to leave this question alone since the first day you posted here, this is the 3rd time...
I was stuck, went into a recurring loop. It looks easy but the expressions are not as simple...
After 2 days seeing no answer submitted, I tried again (sorry to disturb you). Think you need to repost soon :P, sorry...
