If vectors `vec(P),vec(Q)` and `vec(R)` have magnitudes 5,12 and 13 units and `vec P+vec Q=vec R`, the angle between Q and R is:

If vector P, Q and R have magnitude 5,12,and 13 units and vec(P)+vec(Q)=vec(R ) , the angle between Q and R is

If vector P, Q and R have magnitude 5,12,and 13 units and vec(P)+vec(Q)=vec(R ) , the angle between Q and R is

If between vec(P),vec(Q) and vec(R) have magnitudes 5,12 and 13 units and vec(P) + vec(Q) = vec(R) , find the angle between vec(Q) and vec(R) .

If vec P+ vec Q = vec R and |vec P| = |vec Q| = | vec R| , then angle between vec P and vec Q is

if vec(P) xx vec(R ) = vec(Q) xx vec(R ) , then

Three vectors vec(P), vec(Q), vec(R) obey vec(P) + vec(Q) = vec(R) and P^(2) + Q^(2) = R^(2) the angle between vec(P) & vec(Q) is

Three vectors vec P,vec Q,vec R are such that the |vec P|=|vec Q|,|vec R|=sqrt(2)|vec P| and vec P+vec Q+vec R=0 the ange between vec P and vec Q,vec Q and vec R=0 the ange between vec P and respectively

Given that P=Q=R . If vec(P)+vec(Q)=vec(R) then the angle between vec(P) and vec(R) is theta_(1) . If vec(P)+vec(Q)+vec(R)=vec(0) then the angle between vec(P) and vec(R) is theta_(2) . The relation between theta_(1) and theta_(2) is :-
