Let's discuss answers of phy p33

[shressubha]

Did any1 remember d answers 2 the values of M , N and P? What bout problems and solutions to the 2nd xperiment?/

 

[Adham-amr]

M was the gradient..it was 0.26 as my answer said
N was the y-int. it was 0.55 or 0.54 I don't remember actually
and P was 4.7x10^-6 I think? or -8? Don't remember actually
What was the diameter of the wire? First question in the exam?

 

[shressubha]

I got ans as follows:

M: gradient: 0.314
N: Y intercept: 1.73
P: resistivity: 3.59*10^-6
d: diameter: .41mm

did Any1 know the time taken for 1 complete oscillation in 2nd question????? :Search:
I got time period as follows:

1.05s (for a loop made with 100cm string)
0.89s (for a loop made with 50cm string)

:unknown:

Guys please know that there is not fixed answers for your readings, It is a wide range put by examiners..I made the 100 cm loop about 0.86 s for an oscillation and the 50 cm loop about 0.57 s for an oscillation.
Good luck in the structured and MCQs
