2 The electric resistance of a certain wire of iron is R If its length and radius both are doubled then the resistance 1 Will be doubled and the specific resistance will be halved 2 Will be halved and the specific resistance will remain unchanged 3 Will be halved and the specific resistance will be doubled 4 And the specific resistance both will remain unchanged PL Hint R and p is independent of geometry changes
