Question:
A vector a have magnitude 5 unit and an another vector b have magnitude 4 units and making an angle with vector a is 50 .Find vector product
Answer:
Let first vector a = 5
Second vector b = 4
and angle θ = 50°
Now a*b = |a| |b| sinθ n {where n is the unit vector}
=> a*b = 5*4* sin50° n
=> a*b = 20sin50° n
and |a*b| = 20sin50°
