Let \veca,\vecb,\vecc be three coplanar concurrent vectors such that the angles between any two of them are the same. If the product of their magnitudes is 14 and (\veca*\vecb)*(\vecb*\vecc) +(\vecb*\vecc)*(\vecc*\veca) +(\vecc*\veca)*(\veca*\vecb)=168, then |\veca|+|\vecb|+|\vecc| is equal to: | Watch the step-by-step video solution for this NIMCET PYQ.
