In a given ammeter, a student observes that the needle indicates 17 divisions in the ammeter when performing an experiment to verifY Ohm.s law. If the ammeter has 10 divisions between o and 0.5 A, then what is the value of 17 divisions?

Text Solution

Verified by Experts

Since the ammeter has 10 divisions between 0 and 0.5 A, its least count or value of 1 division `=(0.5A)/10 =0.05A`
Therefore, the value of 17 divisions
`=17(0.05A) =0.85A`

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 an internal micrometer, main scale division is of 0.5 mm and there are 50 divisions in circular scale. The least count of the instrument is-

Snell's law relation for air glass boundary is given by equation n_(air) sin theta_(1) = n_(glass) sin theta_(r) . Here angle of refraction in glass is theta_(r) and the angle of incident in air is theta_(i) . The refractive index of air is n_(air)=1 (with negligible uncertainty). In an experiment to verify Snell's the best fit line on a graph between sin theta_(r) (on the y-axis) and sin theta_(i) (on the x-axis) is given by the eqyuation y=(6.66pm0.05)xx10^(-1)x+(0.022pm0.024) . The refractive index of the glass, including the error is reported as 1.abpm 0.0c , where a,b and c are digits after tje decimal point. Calculate value of (a+b-c) .

A student is performing an experiment using a resonance column and a tuning fork of frequency 244s^(-1) . He is told that the air in the tube has been replaced by another gas (assuming that the air column remains filled with the gas). If the minimum height at which resonance occurs is (0.350+- 0.005)m , the gas in the tube is (Useful information : sqrt(167RT) = 640J^(1//2)mol^(-1//2) , sqrt(140RT) = 590J^(1//2)mol^(-1//2) .

Diameter of a steel ball is measured using a Vernier callipers which has divisions of 0.1 cm on its main scale (MS) and 10 divisions of its vernier scale (VS) match 9 divisions on the main scale. Three such measurement for a ball are given as : {:("S.No.","MS (cm)","VS divisions"),(1.,0.5,8),(2.,0.5,4),(3.,0.5,6):} It the zero error is -0.03 cm, then mean corrected diameter is :-

A screw gauge with a pitch of 0.5 mm and a circular scale with 50 divisions is used to measure the thickness of a thin sheet of Aluminium. Before starting the measurement, it is found that when the two laws of the screw gauge are brought in contact, the 45^(th) division coincides with the main scale is barely visible. What is the thickness of the sheet is the main scale reading is 0.5 mm and the 25^(th) division coincides with the main scale line ?

During Searle's experiment, zero of the Vernier sacle lies between 3.20 xx 10^(-2), and 3.25 xx 10^(-2)m of the main scale. The 20^(th) division of the Vernier scale exactly coincides with one of the main scale divisions. When an additional load of 2kg is applied to the wire, the zero of the vernier scale still lies between 3.20 xx 10^(-2), and 3.25 xx 10^(-2)m of the main scale but now the 45^(th) division of Vernier scale coincide with one of the main scale divisions. the length of the thin metallic wire is 2m and its cross-sectional ares is 8 xx 10^(-7)m^(2) . the least count of the Vernier scale is 1.0 xx 10^(-5)m . the maximum percentage error in the Young's modulus of the wire is
