An experiment is conducted to measure the length of a rod using vernier calipers. The main scale reading is , and the vernier scale reading is
divison. The least count of the vernier calipers is
. Calculate the length of the rod.
Answers (1)
Given values:
- Main scale reading
- Vernier scale reading
- Least count of the vernier calipers
The total reading on the vernier calipers can be calculated by adding the
main scale reading and the vernier scale reading:
Total reading
Step 1: Calculate the total reading on the vernier calipers:
Total reading
The least count of the vernier calipers is , which means that one
division on the vernier scale corresponds to .
The number of vernier divisions can be calculated by finding the division on
the vernier scale that aligns with a division on the main scale.
Step 3: Calculate the length of the rod using the actual reading: Length of
rod
So, length of rod is
So. correct option is C
