Given that 
. Two out of the three vectors are equal in magnitude. the mgnitude of tha third vector is √2 time that of the other two. Which of tha following can be the angles between these vectors ?
. Two out of the three vectors are equal in magnitude. the mgnitude of tha third vector is √2 time that of the other two. Which of tha following can be the angles between these vectors ?Options
A.90o, 135o, 135o
B.45o, 45o, 90o
C.30o, 60o, 90o
D.45o, 90o, 135o
Solution
Let P = Q; R =
Since
These are in equilibrium so, they are represented by three sides of a triangle.
Now, |
|= P & |
| = 
. it has been depicted in the figure above. The angles of triangle are 90o, 45o & 45o. So angles between P&Q is 90o, angle between Q&R is 135o and angle between R and P is 135oCreate a free account to view solution
