NEET 2026 Physics question
Savitha, a XI standard student, while conducting an experiment to determine the effective length of a simple pendulum , notes down the data of time taken to complete 30 oscillations as 60 s and hence calculates the length of the simple pendulum as: (Take , and )
Answer: (4)
Solution
Time period . For a simple pendulum , so \frac{gT^2}{4π^2}\frac{9.8 × 4}{4 × 9.8}$
