Question

find the volume of a rectangular block by using vernier Caliper by observation table
​

Answer 1

Answer:

To measure the dimensions of a given regular body of known mass using a Vernier Callipers and hence find its density.

Apparatus

Vernier callipers, a small rectangular metallic block or glass slab of known mass, magnifying lens.

Theory

(i) For measuring dimensions. Same as in Experiment 1 A.

(ii) For volume

Volume of a rectangular block = Length x Breadth x Thickness (height)

Density= Mass/Volume

i.e,.. ρ=m/V
