Question

Find the salar and vector products
of A-2i+7jk and B4i -3j-4k.​

Answer 1

Answer:

Scalar product=A.B

so, Acc.to question

-2×4+7×-3+1×-4=-8-21-4=-17

Vector product=A×B

|i j k|

|-2 7 1|

|4 -3 -4|

Solving ,we get

=>i(-28-(-3))-j(8-4)+k(6-28)

=>25i-4j-22k

Mate I think A=-2i+7j+k is the equation ...

Plzz check it once...
