Jamb Physics Questions - Period of S.H.M

Question 1:
The relationship between the period T and the length T of a smile pendulum is T = 2\( \pi \) \( ( \frac{I}{g}) ^{ \frac{1}{2} } \). From experiment data of T and I, one can obtain the following graphs, i. T vs.I ii. T vs I2 iii. T2 vs. I iv. T vs \( \sqrt{I} \) v. logT vs logI. Which of the following graphs, are linear?
  • A All
  • B Only i and ii
  • C Only iii and iv
  • D Iii,iv and v
  • E None of them

  • B \( 1.5 \frac{ \sqrt{3}}{2} \)s
  • C 2.25s
  • D 1.00s
