The relation between the lengths of the phasors VRN and – VYN is?(a)

1.	The relation between the lengths of the phasors VRN and – VYN is?(a) \|VRN\| > – \|VYN\|(b) \|VRN\| < – \|VYN\|(c) \|VRN\| = – \|VYN\|(d) \|VRN\| >= – \|VYN\|This question was posed to me during an interview.The doubt is from Voltage, Current and Power in a Star Connected System in chapter Polyphase Circuits of Network Theory
Answer» The CORRECT option is (C) \|VRN\| = – \|VYN\| The explanation is: The voltage VRY is found by compounding VRN and VYN reversed. The relation between the lengths of the phasors VRN and – VYN is \|VRN\| = – \|VYN\|.
