I verified and get the answer 0. I was in confusion about using quadratic formula in the vector portion.

AxB gives you a perpendicular vector, not perpendicular *unit* vector. (1) doubletick at the end means you have everything now at your disposal to find the perpendicular unit(1) vector. Hope this makes it clear! |

Video lectures is a good option but in this option we cannot ask any questions. You must seek guidance from the forum and if you belong to an educated family, you must take help from an engineer. Unfortunately, i have no engineer in my family.
