MCQ
Assertion (A): Two vectors are equal when their magnitude and direction both are equal.
Reason (R): For any two vectors $\overrightarrow{ A }$ and $\overrightarrow{ B }$, if angle between them is $\frac{\pi}{4}$ rad, then $\overrightarrow{ A } \times \overrightarrow{ B }=\overrightarrow{ A } \cdot \overrightarrow{ B }$.
  • A
    Both A and R are true and R is the correct explanation of A.
  • B
    Both A and R are true but R is not the correct explanation of A.
  • C
    A is true but R is false.
  • D
    A is false but R is true.
✓

Answer

(c) A is true but R is false.
