Question

Assertion :Let the vectors $P Q, Q R, R S, S T, T U$ and $U P$ represent the sides the regular hexagon
$P Q \times (R S + S T) \neq 0$ Reason: $P Q \times R S = 0$ and $P Q \times S T \neq 0$

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is C Assertion is correct but Reason is incorrect
We have $R S + S T = R T$
As $P Q$ and $R S$ are not parallel to each other.
$P Q \times (R S + S T) = P Q \times R T \neq 0$
Thus assertion is true.Since $P Q$ and $R S$ are not parallel, $P Q \times R S \neq 0$
Therefore reason is false.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica
