● The pendulum p of length 5m Will make more oscillations as compared to q of length 10m.

● Because

t \alpha  \sqrt{l}

Answer: Pendulum p will make more oscillations.

Explanation:

  • We know that the time period of a pendulum T = 2\pi \sqrt{\frac{l}{g} } ,

where l is the length of the pendulum and g is the acceleration due to gravity.

  • For pendulum p,

l= 5 metre.

g= 9.8 ms^{-2}

Then, T_{p} = 2\pi \sqrt{\frac{5}{9.8} } = 4.49 sec.

  • For pendulum q,

l= 10 metre.

g= 9.8 ms^{-2}

Then, T_{q} = 2\pi \sqrt{\frac{10}{9.8} } = 6.35 sec.

Now, for time period 4.49 sec, p makes 1 oscillation.

Therefore, for time period 2 sec, p makes \frac{2}{4.49}  = 0.45 oscillations.

Again, for time period 6.35 sec, q makes 1 oscillation.

Therefore, for time period 2 sec, q makes \frac{2}{6.35} = 0.31 oscillations.

Therefore, pendulum p will make more oscillations.
