If ā,b,c are three vectors such that ` |veca |= 5, |vecb| = 12 and | vecc|=13` and `veca+vecb+vecc=0` then `veca.vecb+vecb.vecc+vecc.veca`

If veca,vecb, vecc are three vectors such that |veca |= 5, |vecb| = 12 and | vecc|=13 and veca+vecb+vecc=0 then veca.vecb+vecb.vecc+vecc.veca is equal to

If veca,vecb,vecc are three vectors such that |veca|=5,|vecb|=12 and |vecc|=13 and veca+vecb+vecc=vec0 ,find the value of veca.vecb+vecb.vecc+vecc.veca .

If veca,vecb and vecc are three vectors such that |veca|=5,|vecb|=12,|vecc|=13 and veca+vecb+vecc=0 then find the value of veca.vecb+vecb.vecc+vecc.veca.

If veca,vecb,vecc are three vectors such that : |veca|=5,|vecb|=12 and |vecc|=13 and veca+vecb+vecc=vec0 , find the value of veca*vecb+vecb*vecc+vecc*veca .

If veca,vecb, vecc are three vectors such that veca + vecb +vecc =vec0, |veca| =1 |vecb| =2, | vecc| =3 , then veca.vecb + vecb .vecc + vecc.veca is equal to

If veca,vecb,vecc are three vectors such that veca+vecb+vecc=vec0 and |veca|=2,|vecb|=3,|vecc|=5 the value of veca.vecb+vecb.vecc+vecc.veca is

If veca,vecb, vecc are three vectors such that veca + vecb +vecc =vec0, |veca| =1 |vecb| =2, | vecc| =3 , then veca.vecb + vecb .vecc +vecc + vecc.veca is equal to
