Q. A person travels towards north by 4 m and then turns to west and travels by 3 m The distance and displacement are

7 m and 5 m

7 m and 7 m

7 m and 1 m

7 m and 3.5 m

Displacement $= C A$
$C A^{2} = C B^{2} + B A^{2} = (3)^{2} + (4)^{2} = 25$
$∴ C A = 5 m$
Distance $= 3 + 4 = 7 m$
Displacement $= 5 m$

Q. A person travels towards north by 4 m and then turns to west and travels by 3 m The distance and displacement are

7 m and 5 m

7 m and 7 m

7 m and 1 m

7 m and 3.5 m

Displacement =CA CA2=CB2+BA2=(3)2+(4)2=25 ∴CA=5m Distance =3+4=7m Displacement =5m

Displacement $= C A$
$C A^{2} = C B^{2} + B A^{2} = (3)^{2} + (4)^{2} = 25$
$∴ C A = 5 m$
Distance $= 3 + 4 = 7 m$
Displacement $= 5 m$
