A women travels a distance of 1m towards north and then 2m towards east and finally 3m towards south find displacement |
|
Answer» 2 √ 2 m EXPLANATION:Given : A women TRAVELS : 1 m towards NORTH = j 2 m towards east = 2 i3 m towards south = - 3 jNet displacement = j + 2 i - 3 j= > 2 i - 2 jHere i represents east direction and - i west direction.j represent north and - j represent south direction!Also these are vector representation!Now magnitude of displacement : = > √ [ ( 2 )² + ( - 2 )² ] m= > √ ( 4 + 4 ) m= > √ 8 m= > 2 √ 2 mHence total displacement is 2 √ 2 m |
