A screw gauge has a least count 0.001 cm and zero error + 0.007 cm. Draw a neat diagram to represent it.

A vernier callipers has a zero error + 0.06 cm. Draw a neat labelled diagram to represent it.

Thickness of a pencil measured by using a screw gauge (least count.001 cm) comes out to be 0.802 cm .The percentage error in the measurement is

A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale: The pitch of the screw gauge is:

In searle's experiment, the diameter of the wire, as measured by a screw gauge of least count 0.001 cm is 0.500 cm. The length, measured by a scale of least count 0.1cm is 110.0cm. When a weight of 40N is suspended from the wire, its extension is measured to be 0.125 cm by a micrometer of least count 0.001 cm. Find the Young's modulus of the meterial of the wire from this data.

A student measured the diameter of a wire using a screw gauge with least count 0.001cm and listed the measurement. The correct measurement is

A student measued the diameter of a small steel ball using a screw gauge of least count 0.001 cm . The main scale reading is 5 mm and zero of circular scale division coincides with 25 divisions above the reference level. If screw gauge has a zero erroof -0.004 cm , the correct diameter of the ball is

The diameter of a wire is measured with a screw gauge having least count 0.01 mm . Out of the following the one which correctly expresses its diameter is

When a screw gauge of least count 0.01 mm is used to measure the diameter of a wire, the reading on the sleeve is found to be 1 mm and the reading on the thimble is found to be 27 divisions.If the zero error + 0.005 cm, what is the correct diameter ?

When a screw gauge of least count 0.01 mm is used to measure the diameter of a wire, the reading on the sleeve is found to be 1 mm and the reading on the thimble is found to be 27 divisions.What is the diameter of the wire in cm ?

A rectangular metal slab of mass 33.333 g has its length 8.0 cm, breadth 5.0 cm and thickness 1mm. The mass is measured with accuracy up to 1 mg with a senstitive balance. The length and breadth are measured with a vernier calipers having a least count of 0.01 cm. The thickness is measured with a screwgauge of least count 0.01 mm. Calculate the percentage accuracy in density from above measurements.
