Question

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 1

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!
