Q.7
1.SCALAR PRODUCT X.Y=|X|.|Y|.Cos theta
→2.3.cos 60
6.1/2
→3.
2.VECTOR PRODUCT is same as dot product but sin theta is taken
2.3.sin 60
6.root 3/2
3 root 3
Q.8
magnitude of A is root over 4+1+1
root 6
magnitude of B is root over 9+16+25
root 50
cos theta =A.B/|A|.|B|
A is 2i+3j ......given in question
substitute the values
