A student performs an experiment for determination of `g(=(4pi^(2)l)/(T^(2))),~~1m`, and he commits an error of `Deltal`.
For `T` he takes the time of `n` oscillations with the stop watch of least count `Delta` and he commits is human error of `0.1sec`. For which of the following data, the measurement of `g` will be most accurate?

A

`{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,5mm,,0.2sec,,10,,5mm):}`

B

`{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,5mm,,0.2sec,,20,,5mm):}`

C

`{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,5mm,,0.1sec,,20,,1mm):}`

D

`{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,1mm,,0.1sec,,50,,1mm):}`

In an experiment of determine acceleration due to gravity by simple pendulum, a student commits 1% positive error in the measurement of length and 3% negative error in the time then % error in g will be

In an experiment to determine acceleration due to gravity, the length of the pendulum is measured as 98 cm be a scale of least count of 1 cm. The period of swing/oscillations is measured with the help of a stop watch having a least count of 1s. The time period of 50 oscillation is found to be 98 s. Express value of g with proper error limits.

A student performs an experiment to determine the Young's modulus of a wire, exactly 2m long, by Searle's method. In a partcular 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 0.4mm with an uncertainty of +-0.01mm . Take g=9.8m//s^(2) (exact). the Young's modulus obtained from the reading is
