Question

While measuring length of an object it was observed that the zero of the vernier lies between 1.4 and
1.5 of the main scale and the fifth division coincides with a main scale division. If the length of the
object measured is l, then the value of (l - 1.4) in terms of the least count C of the instrument is

Answer 1

Answer: 5C

       

EXPLANATION:

Let x=l-1.4  ---------(1)

Then, 1.4 +x +5V =1.4 + 5S

[where S denotes the length of one main scale division and V denotes the length of one vernier scale division.]

Hence,

x= 5S-5V = 5(1S-1V) = 5C
