Two tangent galvanometers having coils of the same radius are connected in series. A current flowing in them produces deflections of $60 °$ and $45 °$ respectively. The ratio of the number of turns in the coil is -

Options:

Answer:

Solution:

In series, current is same in tangent galvanometer.

$B = B_{H} t a n θ \Rightarrow \frac{μ_{0} ni}{2 R} = B_{H} t a n θ$

$∵ i$ is same

$∴ n \propto t a n θ \Rightarrow \frac{n_{1}}{n_{2}} = \frac{t a n 60 °}{t a n 45 °} = \frac{\sqrt{3}}{1}$
