Question

6. Your scale has rough edges near zero. What
errors might occur if you measure the
length of a pen with it? How can you
correct the error?​

Answer 1

There can be errors in measurement from zero. However this can be corrected by keeping the tip of the pen near one instead of zero.

Hope it helps.

Answer 2

Answer:

If we measure the length with the ruler having rough edges near zero than we may measure wrong lengths and the line may not be of correct measurement.

To correct the error we need to measure the length with a ruler having no rough edges.
