Answer» :Given -A (5, 4, 9)B (9, 7, 21)A particle moves from point A to point B.To Find -DISPLACEMENT vector ?Magnitude of Displacement ?SOLUTION -We know that, So, Hence,So, The Final Answer is :Now, Displacement = (4, 3, 12)Squaring and adding : 4² + 3² + 12²⇒ 16 + 9 + 144⇒ 169Finding its SQUARE root : √169 = 13 units.Hence, Magnitude of Displacement = 13 units. |
