The x-component of the resultant of several vectors

Options

A. is equal to the sum of the x-components of the vectors
B. may be smaller than the sum of the magnitudes of the vectors
C. may be greater than the sum of the magnitudes of the vectors
D. may be equal to the sum of the magnitudes of the vectors

Answer

abd

Explanation

A follows from vector addition rule
if `barR =bar a+barb+barc+`
a component of a vector is always less then its hece `R_(x) lt |barR|`
There are no y components `rarr` D is also correct
