MCQ
ફક્ત $a, b, c$ ત્રણ સદિશ $a\times (b\times c) = (a\times b)\times c$, જો.....
- ✓$b × (a × c) = 0$
- B$a .(b × c) = 0$
- C$c × a = a × b$
- D$c × b = b × a$
$\,a \times (b \times c) = (a \times b) \times c$
$ \Rightarrow \,\,(a\,.\,c)\,b - (a\,.\,b)\,c = (a\,.\,c)\,b - (b\,.\,c)\,a$
$ \Rightarrow - \,(a\,.\,b)\,c = - \,(b\,.\,c)\,a$
$ \Rightarrow \,\,(b\,.\,c)\,a - (b\,.\,a)\,c = 0$
$ \Rightarrow \,\,b \times (a \times c) = 0$
