Paheli starts from her home and moves a distance of 4 km towards east. She then turns to her right and covers a distance of 3 km to reach her school. Meanwhile her brother Bujo takes a short and direct route to reach the school. What is the difference between the displacements of Paheli and Bujo? (a)0 km (b)0.5 km (c)1 km (d)1.5 km
Answers
Answer:
look at bro displacement is nothing but shortest distance between intial and final position
as intial and final position of paheli and bujo is same therefore there displacement is also same therefore difference between the displacement bujo and paheli is 0km
Given : paheli starts from her home and moves a distance of 4 km toward east. she turns to her right and covers a distance of 3km to reach her school
her brother bhojoo takes a short and direct route to reach school
To Find : displacement between paheli and bhojoo
Solution:
NORTH
WEST EAST
SOUTH
4 km toward east.
Then Right means 3 km South
Displacement = √4² + 3² = 5 km
her brother bhojoo takes a short and direct route to reach school
His Displacement = 5 km
Both Displacement = 5 km
No difference
0 km is the correct answer
Displacement = Final Position - Initial Position
