C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: C
Solution :
The reduction factor of tangent galvanometer is \[K=\frac{{{B}_{H}}}{G}={{B}_{H}}\times \frac{2r}{n{{\mu }_{0}}}\] Thus reduction factor of a tangent galvanometer depends upon the geometry of its coil. It increases with increase of radius and decreases with increase in number of turn of the coil of the galvanometer.You need to login to perform this action.
