Q. The $x$ and $y$ components of a force are 2 N and $- 3$N. The force is
A) $2\widehat{i} - 3\widehat{j}$
B) $2\widehat{i} + 3\widehat{j}$
C) $- 2\widehat{i} - 3\widehat{j}$
D) $3\widehat{i} + 2\widehat{j}$
Explanation
(a) $\overrightarrow{F} = F_{x}\widehat{i} + F_{y}\widehat{j}$ or $\overrightarrow{F} = 2\widehat{i} - 3\widehat{j}.$
