A tangent galvanometer is connected to an ideal battery. In which of the following options the deflection of magnetic needle of the tangent galvanometer will remain same:

The number of turns in a coil of Galvanometer is tripled, then

Two tangent galvanometers differ only in the matter of number of turns in the coil. On passing current through the two joined in series, the first shows a deflection of 35^@ and the other shows 45^@ deflection. Compute the ratio of their number of turns. Take tan35^@=0*7

A current is sent through two tangent galvenometers in series. The deflectionis seen to be the same in both the galvanometer. Compare the radii of the coils of the galvanometer, if the number of turns in the coil of the first galvanometer is 110 and in the second 25.

Two tangent galvanometers differ only in number of turns in the coil. For same current deflection in them is 45^@ and 35^@ respectively. Find ratio of number of turns of galvanometers.

Two tangent galvanometers P and Q connected in series . The number of turns in P is four times than of Q. When a current is passed through them P shows a deflection of 60^(@) and Q shows a deflection of 30^(@) . What is ratio of the radii of the coils of the two tangent galvanometers ?

Two tangent galvanometer are connetected in series across a battery. The deflections in them found to be 30^(@) and 60^(@) respectively. The ratio of their reduction factors is

The resistance of the coil of a tangent galvanometer is 60Omega . It is connected to a battery of negligible internal resistance. The deflection is found to be 60^(@) . Now a shunt resistance of 30Omega is connected across the coil of the tangent galvanometer. The deflection produced will be
