A particle has the following displacements in succession (i) `12 m` towards East (ii) ` 5 m` towards North and (ii) ` 6 m` vertically. Find the magniude of the resultant displacement.

Explanation

` x= 12 m , y=m , z = 6 m`. ltbRgt Then, ` r= (x^2 +y^2 +z^2)^(1//2)` ltbRgt ` = ( 12^2 + 5^2 + 6^2 ^(1//2)`
`= (12^2 + 5^2 + 6^2)^(1//2)= 14.32 m` .
