Embibe Experts Solutions for Exercise 1: EXERCISE

If $\overrightarrow{P}=\overrightarrow{Q},$ then which of the following is NOT correct? ($\overrightarrow{P}\&\overrightarrow{Q}$ are unit vectors and $P\&Q$ are magnitudes of $\overrightarrow{P}\&\overrightarrow{Q}$)

The magnitude of resultant of the two vectors of magnitude $4$ and $3$ is $1.$ The angle between them is

Given that $\overrightarrow{P}+\overrightarrow{Q}=\overrightarrow{R}$ and $P+Q=R.$ The angle between $\overrightarrow{P}\&\overrightarrow{Q}$ is

For the figure

The resultant of two vectors of equal magnitude is double of either of the vector, the angle between them is

A vector can change if

Given that $\overrightarrow{P}+\overrightarrow{Q}=\overrightarrow{R}$ and that $\overrightarrow{R}$ is perpendicular to $\overrightarrow{P}.$ If $\left|P\right|=\left|R\right|,$ then what is the angle between $P$ and $Q?$

A vector $\overrightarrow{P}$ of length $10$ units makes an angle of $60°$ with a vector $\overrightarrow{Q}$ of length $6$ units. Find the magnitude of the $(\overrightarrow{P}-\overrightarrow{Q})$ and the angle it makes with the vector $\overrightarrow{P}.$
