A tangent galvanometer has a coil with 50 turns and radius equal to 4 cm . A current of 0.1 A is passing through it. The plane of the coil is set parallel to the earth's magnetic meridian. If the value of the earth's horizontal component of the magnetic field is `7xx10^(-5)` Tesla and `mu_(0)=4pixx10^(-7)Weber//ampxxm` then the deflection in the galvanometer needle will be
