Question

while measuring the radius of a circle under the main scale reading is 3.60 cm and the earth Venice scale Division coincides with the main scale calculate the diameter of the cylinder​

Answer 1

Answer:

Given : The main scale reading = 7 cm <br> Vernier scale coincidence = 6 <br> We know that least count of vernier = 0.01 cm <br> The radius of the ball = MSR + VC

LC <br> = 7 cm + 6

0.01 cm <br> = 7 cm + 0.06 cm = 7 . 06 cm
