If ` vec a, vec b and vec c` are unit vectors satisfying the condition `vec a + vec b + vec c = 0` then show that ` vec a. vec b + vec a.vec c + vec b. vec c = -3/2`.

If vec a, vec b and vec c are unit vectors satisfying the condition vec a + vec b + vec c = 0 then shoe that vec a.vec b + vec a.vec c + vec b * vec c = - (3) / (2)

If vec a, vec b, vec c are unit vectors satisfying the condition veca+ vec b+ vec c= 0 then show that vec a. vec b+ vec b.vec c+ vec c. vec a= -3//2 .

If vec a, vec b, vec c are unit vectors such that vec a + vec b + vec c = vec 0 , then the value of vec a . vec b + vec b.vec c + vec c vec a is equal to

If vec a , vec b , vec c are unit vectors such that vec a+ vec b+ vec c= vec0, then write the value of vec a . vec b+ vec b . vec c+ vec c . vec a

If vec a , vec b , vec c are unit vectors and vec a + vec b + vec c = 0 then the evaluate vec a. vec b + vec b.vec c + vec c.vec a .

vec a , vec b , vec c are unit vectors such that vec a+ vec b+ vec c=0. then find the value of vec a. vec b+ vec b.vec c+ vec c. vec a

If vec a, vec b, vec c are unit vectors such that vec a+ vec b+ vec c = vec 0 , then find the value of vec a* vecb + vec b* vec c +vec c* veca .

If vec a,vec b, and vec c are unit vectors such that vec a+vec b+vec c=0, then find the value of vec a*vec b+vec b*vec c+vec c*vec a

If vec a, vec b, vec c are unit vectors such that vec a+ vec b+ vec c =0 , find the value of vec a.vec b+ vec b .vec c + vec c. vec a .

Three vectors veca, vec b and vec c satisfy the condition vec a + vec b + vec c = 0 .Evaluate the quantity. mu = vec a.vec b + vec b.vec c+ veca.vec c if |vec a| = 1, |vec b| = 4, |vec c| = 2
