The magnitude of zero error of the spring balance and least count of the measuring cylinder

A

2.5g and 0.1 mL

B

5.0g and 0.1mL

C

2.5g and 0.2 mL

D

5.0g and 0.2mL

Text Solution

Verified by Experts

The correct Answer is:
D
The pointer in the spring balance lies 1 division`(=2.5g)` above the zero mark. As such the zero error is `(25.0g-0.0g)/(5" divisions")=5.0g`
least count of measuring cylinder `=(2mL-1mL)/(5 "division")=0.2mL`

While determining the density of a copper piece using a spring balance and a measuring cylinder, Seema carried out the following procedure : (i) noted the water level in the measuring cylinder without the copper piece. (ii) immersed the copper piece in the water. (iii) noted the water level in the measuring cylinder with the copper piece inside it. (iv) removed the copper piece from the water and immediately weighed it using a spring balance. The wrong step in the proceedure is :
