Q. A couple consists of a force P acting at a point A whose coordinates are (-1,2,4) m and force - F acting at a point whose coordinates are (2,3, -2)m. If F = 3i + 2j - 4k in kg units the moment of the couple in kg - m units would be

• (A) 8i - 6j - 3k
• (B) 12i - 3j + k
• (C) 16i - 12j - 6k
• (D) 4i - 3j + k
