Weekly Test of physics Topic Vernier Caliper

What is the primary purpose of a Vernier caliper?

• Measuring temperature

• Measuring length, width, and height

• Measuring weight

• Measuring time

The Vernier scale on a Vernier caliper is used to:

• Measure large lengths

• Measure small lengths with high precision

• Measure angles

• Measure weights

The main scale of a Vernier caliper is typically graduated in:

• Centimeters

• Millimeters

• Inches

• Meters

What is the purpose of the sliding jaw on a Vernier caliper?

• To measure inner diameters

• To measure outer diameters

• To measure angles

• To calibrate the instrument

The smallest reading that can be taken on a Vernier caliper is:

• 0.1 mm

• 0.01 mm

• 1 mm

• 0.5 mm

To take an accurate measurement using a Vernier caliper, one must ensure that the caliper's jaws are:

• Dirty for better grip

• Lubricated with oil

• Closed firmly on the object being measured

• Partially open to avoid damage

The least count of a Vernier caliper having 20 divisions on its Vernier scale and 1 mm on its main scale is:

• 0.05 mm

• 0.02 mm

• 0.1 mm

• 0.5 mm

Which part of a Vernier caliper is used to lock the measurement in place?

• Main scale

• Vernier scale

• Locking screw

• Sliding jaw

When reading the measurement from a Vernier caliper, which part of the Vernier scale should be aligned with the main scale to get the reading?

• Highest line on the Vernier scale

• Lowest line on the Vernier scale

• Any line on the Vernier scale

• Any line on the main scale

Which type of Vernier caliper is best suited for measuring the thickness of small objects like paper sheets or thin wires?

• Depth Vernier caliper

• Inside Vernier caliper

• Outside Vernier caliper

• Odd-leg Vernier caliper
