Error committed by a student in removing the parallax is

Explain parallax.

Observe the above experimental setup. The student had committed a mistake in arranging the apparatus. What was it ?

If the error committed in measuring the radius of the circle is 0.05%, then the corresponfing error in calculating the area is a) 0.05% b) 0.0025% c) 0.25% d) 0.1%

What is meant by parallax?

If the error committed in measuring the radius of a circle is 0.01% , find the corresponding error in calculating the area.

If the error committed in measuring the radius of a circle is 0.01% , find the corresponding error in calculating the area.

If the error committed in measuring the radius of a circle is 0.01% , find the corresponding error in calculating the area.

If the error committed in measuring the radius of a circle is 0.01% , find the corresponding error in calculating the area.
