Question

a body moves 6M North 8m East and 10 M vertically upwards the resultant displacement of body from its initial position is

Answer 1

Hey mate,, here is ur ans...

this would form a cuboidal shape with

length 6m, breadth 8m and height 10 m

the resultant displacement would be diagnol of this cuboid

√6²+8²+10²

√200

14.1421m —> resultant displacement of body.

#hope it helps

Answer 2

GIVEN :-

A boy move 6 m north 8 m east and 10 m vertically upwards.

TO FIND :-

The resultant displacement from the initial position.

PRE-REQUISITE :-

Displacement is the shortest length between the initial position and the final position.

OR

Displacement is the change in position vector.

SOLUTION :-

If a body moves 6 m North, 8 m East and 10 m vertically upwards then its resultant displacement from initial position will be in the form of a cuboid with length 6 m,  breadth 8 m and height 10 m.

And the resultant displacement would be the diagonal of this cuboid.

So, the diagonal of a cuboid :-

√(6²+8²+10²)

= √200

= √(100 × 2)

= 10√2

∴ So, the displacement of the boy from his initial position is 10√2 units.
