Question

2. Two vectors are as follows V. = 3i+8; and V, = 9;+4j. Find t
magnitude of the scalar product of these two vectors.
a. 27
b. 32
C.72
d. 59
Sol:
Correct option is (d)
​

Answer 1

Answer:

b.32 is the correct answer

Answer 2

Answer:

d)59

Step-by-step explanation:

v.

=3i+8

v

=9+4j

(3i+8)(9+4j)

27i+12ij+72+32j

i (27+12j)+72+32j
