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
