Explanation:
Let n be the number of the vernier scale division which coincides with the main scale division. Rotate the vernier caliper 90° and repeat the steps 4 and 5 for measuring the internal diameter in perpendicular direction. To measure the depth, find the total reading and zero correction.

Answer:
F₁ = 10.64 N
Explanation:
The pressure is transmitted equally from the first piston to the second piston:
where,
F₁ = Force applied by compressed air on first piston = ?
F₂ = Weight lifted by second piston = 66.5 N
r₁ = radius of first piston = 10 cm
r₂ = radius of second piston = 25 cm
Therefore,
<u>F₁ = 10.64 N</u>
