Q29 of 43 Page 85

A body moves 6 m north, 8 m east and 10m vertically upwards. What is its resultant displacement from the initial position?

Let

North be positive x-axis


East be positive y-axis


Upwards be positive z-axis


Let be the displacements along north, east and upward direction respectively.


Then,


, ,


So, net displacement =



Magnitude of displacement:
