A drone flies from point P(1, 2, 3) to point Q(4, 6, 3) in a Cartesian coordinate system. Calculate the magnitude of its displacement.
Q1. A drone flies from point P(1, 2, 3) to point Q(4, 6, 3) in a Cartesian coordinate system. Calculate the magnitude of its displacement.
Answer: 5 units
Explanation: The displacement vector is (4-1)i + (6-2)j + (3-3)k = 3i + 4j. Magnitude is 5. Option A is the sum of coordinates.
