Question
1)Can you help me get the zero error (divisions) 2)what is zero error (in units)
Expert Solution
Step 1

For the problem given, no measuring instrument is given.

We consider the measuring instrument as Vernier caliper.

Zero Error-

 When the zero of main scale and measuring scale like Vernier caliper do not coincide and there will be  lag of some value which  is called zero error.

Zero error=n×Least countn= number of divisions on vernier scale.

Least count-

The smallest and accurate value in the measured quantity that can be concluded on the instrument's scale(Vernier caliper) is known as Least count.
