In a meter bridge experiment, two resistances $X$ and $Y$ in the two gaps give a null point dividing the wire in the ratio $2 : 3$. When each resistance is increased by $30 \text{ } \Omega$, the null point divides the wire in the ratio $5 : 6$. The resistances $X$ and $Y$ are respectively:

  • A
    $20 \text{ } \Omega, 30 \text{ } \Omega$
  • B
    $22 \text{ } \Omega, 33 \text{ } \Omega$
  • C
    $32 \text{ } \Omega, 48 \text{ } \Omega$
  • D
    $40 \text{ } \Omega, 60 \text{ } \Omega$

The experimental setup of a meter bridge is shown in the figure. If the null deflection point of the galvanometer is at distance $x$ from end $A$,what will be the new null point if the radius of the wire $AB$ is doubled?

$A$ wire of length $10 \ cm$ and radius $\sqrt{7} \times 10^{-4} \ m$ is connected across the right gap of a meter bridge. When a resistance of $4.5 \ \Omega$ is connected in the left gap using a resistance box,the balance length is found to be at $60 \ cm$ from the left end. If the resistivity of the wire is $R \times 10^{-7} \ \Omega \ m$,then the value of $R$ is:

In a meter bridge,the wire of length $1\, m$ has a non-uniform cross-section such that the variation $\frac{dR}{d\ell}$ of its resistance $R$ with length $\ell$ is $\frac{dR}{d\ell} \propto \frac{1}{\sqrt{\ell}}$. Two equal resistances are connected as shown in the figure. The galvanometer has zero deflection when the jockey is at point $P$. What is the length $AP$?
