1 / 61 2 / 61 3 / 61 4 / 61

If any two vectors of scalar triple product are equal, then its value is equal to

5 / 61

The angle in semi-circle is equal to:

6 / 61 7 / 61 8 / 61 9 / 61

. If the scalar product of three vectors is zero, then vectors are

10 / 61 11 / 61 12 / 61 13 / 61 14 / 61 15 / 61 16 / 61

Cross product or vector product is defined

17 / 61 18 / 61 19 / 61 20 / 61 21 / 61 22 / 61 23 / 61 24 / 61

If the cross product of two vectors is zero, then the vectors must be

25 / 61

. If the dot product of two vectors is zero, then the vectors must be
