EasyWhich of the following statements is not true?
- AWhile taking readings of a tangent galvanometer,the plane of the coil must be set at right angles to the earth's magnetic meridian.
- B$A$ short magnet is used in a tangent galvanometer since a long magnet would be heavy and may not easily move.
- CMeasurements with the tangent galvanometer will be more accurate when the deflection is around $45^\circ$.
- D$A$ tangent galvanometer cannot be used in the polar region.

View SolutionTwo bar magnets $A$ and $B$ are geometrically similar but the magnetic moment of $A$ is twice that of $B$. $T_1$ is the time period of oscillation when their like poles are kept together. When unlike poles are kept together,the time period of oscillation is $T_2$. The ratio $T_1: T_2$ will be
