The diameter of the steel ball is measured using a vernier caliper which has divisions of 0.1 cm on its main scale nad 10 division of its vernier scale match 9 division on the main scale. Three such measurements for a ball are as follows.

If the zero error is `0.03cm`, then mean corrected diameter is ............. cm.

A

0.56

B

0.53

C

0.59

D

0.52

Text Solution

Verified by Experts

The correct Answer is:
C

Least count = 0.01 cm
`ZE=-0.03cm`

`"Mean "=(0.61+0.57+0.59)/(3)`
`=1.77`
`therefore" Mean corrected diameter"=0.59cm`

An amateur astronomer wishes to estimate roughly the size of the Sun using his crude telescope consisting of an objective lens of focal length 200 cm and an eyepiece of focal length 10 cm. By adjusting the distance of the eyepiece from the objective, he obtains an image of the Sun on a screen 40 cm behind the eyepiece. the diameter of the sun's image is measured to be 6.0 cm. What is his estimate of the Sun's size given that the average Earth-sun distance is 1.5 xx 10^(11) m ?
