In a specially designed vernier calipers, 10 divisions of the vernier scale are equal to 4 divisions of the main scale. In the following figure, the zero error and a measurement are shown. In the zero error, the 5^(th) and the 10^(th) divisions of the vernier coincides with 1 mm and 3 mm mark on the main scale respectively and in the measurement, the 2^(nd) and the 7^(th) divisions of the vernier scale coincide with the 23 mm and 25 mm mark on the main scale respectively as shown in the figure. Report the length measured with due regards to the error.

A student performs an experiment to determine the Young's modulus of a wire, exactly 2m long, by Searle's method. In a particular reading, the student measures the extension in the length of the wire to be 0.8mm with an uncertainty of +- 0.05mm at a load of exactly 1.0kg , the student also measures the diameter of the wire to be 04mm with an uncertainty of +-0.01mm . Take g=9.8m//s^(2) (exact). the Young's modulus obtained from the reading is

The pitch of a screw gauge is 1 mm and there are 100 division on the circular scale. While measuring the diameter of a wire, the linear scale reads 1mm and 47th division on circular scale coincides with the reference line. The length of the wire is 5.6 cm. Find the curved surface area (in cm^2) of the wire in proper significant figures.

In an experiment to determine an unknown resistance, a 100 cm long rets tance wire is used. The unknown resistance is kept in the left gap and a known resistance is put into the right gap. The scale to measure length has a least count 1 mm. The null point B is obtained at 40.0 cm from the left gap. We shell determine the percentage error in the computation of unknown resistance.

A screw gauge gives the following reading when used to measure the diameter of a wire. Main scale reading =0mm , circular scale reading =52 divisions. Given that 1mm on main scale corresponds to 100 divisions of the circular scale. The diameter of the wire from the above data is

In Young's double slit experiment the fringes are formed at a distance of 1 m from double slit of separation 0.12 mm calculate. (i). The distance of 3rd dark band from the centre of the screen. (ii). The distance of 3rd bright band from the centre of the screen, Given lambda=6000Å

A brass rod of length 50 cm and diameter 3.0 mm is joined to a steel rod of the same length and diameter. What is the change in length of the combined rod at 250 ^(@) C . if the original lengths are at 40.0 ^(@) C ? Is there a "thermal stress developed at the junction ? The ends of the rod are free to expand (Co-efficient of linear expansion of brass = 2.0 xx 10^(-5) K^(-1) , " steel " = 1.2 xx 10^(-5) K^(-1)) .

The length l , breadth b, and thickness t of a block of wood were measured with the help os a measuring scale. The results with permissible errors ( in cm) are l = 15.12 +-0.01, b = 10.15+-0.01 , and t = 5.28 +- 0.01 . The percentage error in volume up to proper significant figures is

Internal micrometer is a measuring intrument used to measure internal diameter (ID) of a large cylinder bore with high accuracy. Construction is shown in figure. There is one fixed rod B (to the right in figure) and one moved rod A (to the left in figure). It is based on the particle of advancement of a screw when it is rotated in a nut with internal threads. Main scale reading can be directly seen on the hub which is fixed with respect to rod B. When the cap is rotated rod A moves in or cut depending on direction of rotation. The circular scale reading is seen by checking which division of circular scale coincide with the references line This is to be multiplied by LC to get circular scale reading. Least count = value of 1 circular scale division = ("pitch")/("number of division on circular scale") Length of rod A is chosen to match the ID(PQ) to be measured. Zero error is checked by taking reading between standard blocks fixed at normal value of ID to be measured. Zero error is positive if cap end is one the right of the main scale and negative it is on the left side. In the above instrument, while measuring an internal diameter. ID is set of 321 mm with no zero error. It cap end is after n^(th) division adn 17^(th) division of main scale coincides with the reference line, the ID is -
