A room has dimensions `3 m xx 4 m xx5 m. A fly starting at one cronet ends up at the diametrically opposite corner. (a) What is the magnitude of its displacement ? (a) What is the magnitude of its displacement ? (b) If the fly wer to walk, what is the length of the shortest pothe it cantake ?

Answer

`sqrt(50)m, sqrt(74)m`

Explanation

(i) `|"displacement"|=sqrt((3)^(2)+(4)^(2)+(5)^(2))=sqrt(50)m`

(ii) `L=sqrt((7)^(2)+(5)^(2))=sqrt(74)m`
