Q. 8

# If the line

Given: A(7, p, 2) and B(q, -2, 5), line segment joining these two points will be, AB = (q-7)i + (-2-p)j + 3k

And the line segment joining C(2, -3, 5) and D(-6, -15, 11) will be, CD = -8i – 12j + 6k

Then, the angle between these two line segments will be 0 degree. So, the cross product will be 0.

ABCD = 0

ð ((q-7)i + (-2-p)j + 3k)( -8i – 12j + 6k) = 0

Thus, solving this we get,

p = 4 and q = 3
