Question

A hall has the dimensions 10m x 10m x 10m.Physics A fly starting at the corner ends up at the diagonally opposite corner. The magnitude o its displacement is nearly?

Answer 1

the diagonal of a cube is 'side of cube×cube root 3'

So,diagonal=10×cube root 3
=10×3^1/3m

and this is the magnitude of displacement of the fly.
