A) \[(0.25\pm 0.08)m\]
B) \[(0.25\pm 0.5)m\]
C) \[(0.25\pm 0.05)m\]
D) \[(0.25\pm 0.135)m\]
Correct Answer: A
Solution :
[a] Error in AB \[=\pm \left( \frac{\Delta A}{A}+\frac{\Delta B}{B} \right)AB=\pm \left[ \frac{0.5}{2.5}+\frac{0.01}{0.10} \right][0.25]\] \[=\pm 0.075=\pm 0.08\] Therefore, \[AB=(0.25\pm 0.08)m\]You need to login to perform this action.
