Option 3 : 0.35°

__Concept:__

Resolution of an encoder can be given in number of bits or degrees.

Resolution depends on the number of tracks on the code disk.

For an N number of tracks (encoder bits), the resolution is given by

\(Resolution = \frac {360}{2^N}\)

__Calculation:__

Given N = 10,

\(\Rightarrow Resolution = \frac {360}{2^{10}} = 0.35 \ degree \)
