Which of the below given is the correct formula for the distance between two skew lines l1 and l2? |
| A. | d= ( left | frac{( vec{b_1} vec{b_2}).(a_2-a_1)}{| vec{b_1} vec{b_2}|} right | ) |
| B. | 2d= ( left | frac{( vec{b_1}- vec{b_2}).(a_2-a_1)}{| vec{b_1}- vec{b_2}|} right | ) |
| C. | d= ( left | frac{( vec{b_1} vec{b_2}).(a_2.a_1)}{3| vec{b_1} vec{b_2}|} right | ) |
| D. | d<sup>2</sup>= ( left | frac{( vec{b_1} vec{b_2}).(a_2-a_1)}{| vec{b_1}- vec{b_2}|} right | ) |
| Answer» B. 2d= ( left | frac{( vec{b_1}- vec{b_2}).(a_2-a_1)}{| vec{b_1}- vec{b_2}|} right | ) | |
