Question

Displacement vectors of 10 m west and 14 m west make a resultant vector that is _____. 10 m west 14 m west 6 m west 24 m west

Answer 1

The correct answer is 24 m west.

Explanation: Let west be the positive direction along x axis.

First displacement vector be a = +10 m

second displacement vector be b = +14 m

Using vector addition,

Resultant vector=
`a+b` =
`(+10)+(+14)=+24`

The magnitude of the resultant vector is 24 m and the positive sign signifies that it is in the west direction.
