If \(\overrightarrow{\mathrm{a}}\), \(\overrightarrow{\mathrm{b}}\), \(\stackrel{\rightharpoonup}{\mathrm{c}}\) are any vectors then which one of the following is a wrong statement.
- \(\overrightarrow{\mathrm{a}}\) + \(\overrightarrow{\mathrm{b}}\) =
+ \(\overrightarrow{\mathrm{a}}\) - \(\overrightarrow{\mathrm{a}}\).\(\overrightarrow{\mathrm{b}}\) = \(\overrightarrow{\mathrm{b}}\).\(\overrightarrow{\mathrm{a}}\)
- \(\overrightarrow{\mathrm{a}}\) × \(\overrightarrow{\mathrm{b}}\) = \(\overrightarrow{\mathrm{b}}\) × \(\overrightarrow{\mathrm{a}}\)
- \(|\overrightarrow{\mathrm{a}} \times \overrightarrow{\mathrm{b}}|=|\overrightarrow{\mathrm{b}} \times \overrightarrow{\mathrm{a}}|\)
Answer
(C) a × b = b × a
