Question

3. A hall has the dimensions 10mx10mx10m. A
fly starting at one corner ends up at a diagonally opposite corner. The magnitude of
its displacement is nearly:​

Answer 1

Given: Dimensions of Hall = 10 m × 10 m × 10 m

To find: Displacement from one corner to another corner

Hall is in shape of Cube.

Length of longest diagonal of cube is given by,

Diagonal of cube=√3 × Length of edge

Displacement = √3 × 10 = 1.732 × 10 = 17.3 m

Therefore, Displacement of Fly is 17.3 m
