Two resistors are connected in parallel b/w A and B to give a net resistance of 2 ohms. When one of these resistors is broken, the net resistance becomes a 3 ohms. What is the resistance of the resistor that was broken?

the net resistanceR_{eq}=2 ohms
when one of the resistance is broken the net resistance is only one of the resistance i.e.R_{1}=3 ohms.
1/R_{eq}=1/R_{1}+1/R_{2}.
soR_{2}=6 ohms.
