If \(\overrightarrow{\mathrm{a}}\) and \(\overrightarrow{\mathrm{b}}\) are two vectors, then -

\(|\overrightarrow{\mathrm{a}} \times \overrightarrow{\mathrm{b}}| \geq|\overrightarrow{\mathrm{a}}||\overrightarrow{\mathrm{b}}|\)
\(|\overrightarrow{\mathrm{a}} \times \overrightarrow{\mathrm{b}}| \leq|\overrightarrow{\mathrm{a}}||\overrightarrow{\mathrm{b}}|\)
\(|\overrightarrow{\mathrm{a}} \times \overrightarrow{\mathrm{b}}|>|\overrightarrow{\mathrm{a}}||\overrightarrow{\mathrm{b}}|\)
\(|\overrightarrow{\mathrm{a}} \times \overrightarrow{\mathrm{b}}|<|\overrightarrow{\mathrm{a}}||\overrightarrow{\mathrm{b}}|\)

Answer

(B) | a b | | a || b |
