Displacement and direction
==================================☆
As the boy travel 3 km north.
And then turns to the east and move 4 kilometre.
Now we can use the Pythagoras Theorem to solve this problem.because this is making and right angle triangle.
whose base is from point to the north and height is the from Nach to the East direction.
For finding displacement we have to find the hypotenuse of this right angle triangle.
(PE)^2 = (PN)^2+(NE)^2
(PE)^2 = (3)^2+(4)^2
PE = root(9+16)
PE = 5 KM
So the net displacement is 5 km.in north east direction.
