["If "vec P*vec Q],[=PQ" then angle between "vec P" and "vec Q" is "]

If |vec P xx vec Q|=PQ then the angle between vec P and vec Q is

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

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 :-

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 :-

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 :-

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 vec(p)*(vec(P)+vec(Q))=P^(2) then the angle between vec(P)andvec(Q) is

Given vec(p)*(vec(P)+vec(Q))=P^(2) then the angle between vec(P)andvec(Q) is

vec P+vec Q+vec R=0 and vec |p|=8,vec |Q|=15 and vec |R|=17 angle between vec P and vec Q is

If |vec(P) + vec(Q)| = |vec(P) - vec(Q)| , find the angle between vec(P) and vec(Q) .
