    Please, check the relationship between Period of oscillation, T and Inertia again. It should be L raised to power 2 and the denominator should have d/2 too

      Unless d/2 is equal to L, which is not...

      Thanks for your comment. The formula used is correct. L raised to the power 2 is also 1 and has no significance since the length of the meter rule is 1m. The value of d has no relevance in the vertical oscillation, besides it is held constant all through the experiment. Thanks

    Plz check weac practical 2009 and give the formula to manipulate. Thanks

      Okay. I will attend to that soon

    I think the graph is negative graphy with what you plot and negative slope is expected

      Thanks for your comment
      1. If the original function has a positive slope, the inverse function will also have a positive slope. For instance y = f(X) = 2X . Its inverse will have a positive slope
      2. If the original function has a negative slope for instance y = f(X) = -2x, the inverse function will also have a negative slope

    My observation is that the graph is a negative graph which means you were supposed to have a negative slope as well. Is the graph a function?

    Good day sir, nice work. Plz what formula can we use to find the period T if the mass(g) is kept constant and the height h (xy) n (pq) r being varied 50cm, 60cm, 70cm, 80cm, 90cm.

      Thanks for your comment. The instructions says that the teachers should provided a set of masses, which means that mass would be varied.
      Then please what do you mean by 'r'? Do you mean 'd' that I used in the question ie the distance between the two strings. Let me know

      I am not talking of this particular experiment. I am saying if the question is changed and the mass is kept constant and the height of the thread is now varied say 50cm, 60cm, 70cm, 80cm, 90cm. What formula can we use. Thanks for work.
