    Yup luckily no fluctuations in the ammeter and voltmeter readings. Higher oscillation for second value of T(common sense) and my results supported the relationship. You can opt for either support or not support, both are correct but you have to justify it using percentage difference in the values of k.

    Doesn't matter, you still get 2 marks for the gradient and intercept and 2 marks for P and Q constants(provided that your units were cm and V which were the correct units, respectively)

    But doing it in cm is also correct for the question started asking the length to be in 40 cm.
    That is why I did my whole question taking lengths in cm.
