Question

Calculate the correct reading of the vernier caliper L.C.0.01cm

Answer 1

$\huge {\boxed {\mathtt {\underline \color {gold} {ANSWER :- }}}}$

$\implies$ L.C. = 0.01 cm

Error = + 0.02 cm ⇒ Positive zero

error = + 0.02 cm

ᴍain scale reading (MSR) = 3.60 cm 8th vernier

scale coincides with main scale

⇒ vernier coincidence (VC) = 8

We know ᴛʜᴀᴛ :-

Correct diameter = [main scale reading+ (L.C × V.C)] - (error)

$\implies$ $\bf { <strong>[3.60 + (0.01 × 8)] - [+ 0.002]</strong> }$

$\implies$ $\bf{ (<strong>3.60 + 0.08</strong>)- (+0.02) }$

$\implies$ $\bf { <strong>3.68 - 0.02</strong> }$

$\implies$ $\bf {<strong>3.66 cm</strong>}$

$\therefore$ ${Correct radius }$ $\implies$ $\frac {Diameter}{2}$

$\implies$ ${1.83 cm}$

$\implies$ $\huge {\underline {\underline {\mathfrak \color {purple} {1.83}}}}$
