13. A body moves 6 m north, 8 m east and 10 m vertically upwards, the resultant displacement of body from its initial position is(1) 102 m(2) 10 m(4) 20 m |

Answer» Here 10M is VERTICALLY upwards that means it is in z AXIS in upward direction and not north. This is an IMPORTANT point do clear it.so final Displacement is= √ x^2 + y^2 + z^2= √ 8^2 + 10^2 + 6^2= √200= 10 √2 m.Hope it helps! |
