Question

If the least count of vernier caliper is 0.01 cm and least count of sphero meter is 0.001 cm then which will be the more accurate and why?
Answer fast plz.


​

Answer 1

Answer:

Correct option is

C

1.83

L.C. = 0.01 cm

Error = + 0.02 cm ⇒ Positive zero

error = + 0.02 cm

main scale reading (MSR) = 3.60 cm 8

th

vernier scale coincides with main scale

⇒ vernier coincidence (VC) = 8

We know that

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

= [3.60 + (0.01 × 8)] - [+ 0.002]

= (3.60 + 0.08)- (+0.02)

= 3.68 - 0.02

= 3.66 cm

∴correctradius=

2

diameter

=

2

3.66

=1.83cm
