Question

Let the positive  x-axis and positive  y-axis represents East and North direction respectively. A boy standing at the meeting point of axes starts walking 5 units east and then 3 units south. He, then, turns back and covers 5 more units. At what place is the boy standing and what direction is he facing now? pls pls answer this question... I will mark the first correct answer as brainliest​

Answer 1

Step-by-step explanation:

ANSWER

As per the condition, the particle moves 3m in the east (x-direction),

4 m in the north ( y-direction) and 

5 m due in the z-direction 

(i) if the movement of the particle is to be speculated in the vectors term then it can be written as

R=3i+4j+5k

ii) The question should find the displacement of the particle from the origin,

The net displacement will be =(3²+4²+5²)

=50

=7.07

The displacement is 7.07 units in the direction of vector 3i + 4j + 5k
