find the scalar product of the two vector
A=4i+3j and B=5i-2j.
what is the
magnitude of the vector product?​

Answer 1

Answer:

scalar product is A.B = (4i×5i)+(3j× -2j)

= 20 (1) + (-6)(1) = 14

Answer 2

Hey User!

Here's your answer!

• Scalar product of the two vector = A.B

a) ( 4î + 3j ) . ( 5î - 2j ) = ( 4 × 5 ) + ( 3 × -2 ) = 20 - 6 = 14

Hope it helps!
