A screw gauge gives the following readings when used to measure the diameter of a wire:

Main scale reading: \(0\) mm

Circular scale reading: \(52\) divisions

Given that \(1\) mm on the main scale corresponds to \(100\) divisions on the circular scale, the diameter of the wire that can be inferred from the given data is:

1. | \(0.26\) cm | 2. | \(0.052\) cm |

3. | \(0.52\) cm | 4. | \(0.026\) cm |

A student measured 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 the screw gauge has a zero error of \(-0.004\) cm, the correct diameter of the ball is:

1. \(0.521\) cm

2. \(0.525\) cm

3. \(0.053\) cm

4. \(0.529\) cm

The pitch of a screw gauge is \(1~\)mm and there are \(100\) divisions on the circular scale. While measuring the diameter of a wire, the linear scale reads \(1\) mm and \(47\)^{th} division on the circular scale coincides with the reference line. The length of the wire is \(5.6\) cm. Curved surface area (in cm^{2}) of the wire in appropriate number of significant figures will be:

1. \(2.4\) cm^{2}

2. \(2.56\) cm^{2}

3. \(2.6\) cm^{2}

In an experiment, the height of an object measured by a vernier callipers having least count of \(0.01~\text{cm}\) is found to be \(5.72~\text{cm}\). When no object is there between jaws of this vernier callipers, the reading of the main scale is \(0.1\) cm and the reading of the vernier scale is \(0.3~\text{mm}\). The correct height of the object is:

1. \( 5.72 ~\text{cm} \)

2. \( 5.59~\text{cm} \)

3. \( 5.85~\text{cm} \)

4. \( 5.69~\text{cm} \)
