The two secondaries of a linear variable differential transformer (LVDT) showed a magnitude of $2 \mathrm{~V (RMS)}$ for zero displacement position of the core. It is noted that the phase of one of the secondaries has a deviation of one degree from the expected phase. Other than this deviation, the LVDT is ideal.
If the differential output sensitivity of the LVDT is $1 \; \text{mV (RMS)/1} \; \mu \mathrm{m}$, the output for zero displacement is____________$\mu \mathrm{m}$ (rounded off to one decimal place).
