Physics Question from JEE Main 2026 · 24 January, Shift 1

Two resistors 2Ω2\,\Omega and 3Ω3\,\Omega are connected in the gaps of a bridge as shown in the figure. The null point is obtained with the contact of jockey at some point on wire XYXY. When an unknown resistor is connected in parallel with 3Ω3\,\Omega resistor, the null point is shifted by 22.5cm22.5\,\text{cm} towards YY. The resistance of unknown resistor is _____ Ω\Omega.

A meter bridge wire from X to Y with two resistors of 2 ohm and 3 ohm in the two gaps above the wire, and a jockey contact connected to a point between them on the bridge wire.
