a man goes 10m towards north,then 20m towards east then displacement is
ishanaghosh:
Going towards north and then east the man's direction changes perpendicularly. We know, displacement is the shortest distance between initial and final positions. So, by joining those positions we get a right angled triangle. Now by Pythagorean theorem, displacement=√(10^2 + 20^2) =√500=10√5 m. This is the reqd. displacement.
