In a circuit for finding the resistance of a galvanometer by half deflection method, a 6 V battery and a high resistance of 11kΩ are used. The figure of merit of the galvanometer is 60μA/division. In the absence of shunt resistance, the galvanometer produces a deflection of θ=9 divisions when current flows in the circuit. What value of shunt resistance will cause the deflection to become θ/2?
a. 55Ω
b. 110Ω
c. 220Ω
d. 550Ω
