Let the vectors PQ→,  QR→,  RS→,  ST→,  TU→,\overrightarrow {PQ} ,\,\,\overrightarrow {QR} ,\,\,\overrightarrow {RS} ,\,\,\overrightarrow {ST} ,\,\,\overrightarrow {TU} , and UP→,\overrightarrow {UP} , represent the sides of a regular hexagon.

STATEMENT-1: PQ→×(RS→+ST→)≠0→.\overrightarrow {PQ} \times \left( {\overrightarrow {RS} + \overrightarrow {ST} } \right) \ne \overrightarrow 0 . because
STATEMENT-2: PQ→×RS→=0→\overrightarrow {PQ} \times \overrightarrow {RS} = \overrightarrow 0 and PQ→×ST→≠0→  .\overrightarrow {PQ} \times \overrightarrow {ST} \ne \overrightarrow 0 \,\,.

Multiple Choice Options

  • A Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
  • B Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1.
