Q. If a man goes $10 m$ toward north and $20 m$ toward east, then his displacement is

$22.5 m$

$25 m$

$25.5 m$

$30 m$

Displacement $= A C = (A B)^{2} + (BC)^{2}$
$= (10 m)^{2} + (20 m)^{2}$
$= 100 + 400 \approx 22.5 m$

Q. If a man goes 10m toward north and 20m toward east, then his displacement is

22.5m

25m

25.5m

30m
