Gravity can be determined by launching an object upward and recording the time it takes to cross two specific points during its ascent and descent.
For the figure , which option is correct.
1
\( g = \frac{4h}{T_A^2 +T_B^2} \)
2
\( g = \frac{8h}{T_A^2 - T_B^2} \)
3
\( g = \frac{8h}{T_A^2 +T_B^2} \)
4
\( g = \frac{4h}{T_A^2 - T_B^2} \)
