Answer 1

$here \\ \\ T = \sqrt{ \frac{2L}{g} } + \frac{L}{V } \\ \\delta \: T = deta \: A + delta \: B \\ \\ delta \: T = \sqrt{ \frac{2}{g} } \: \times \frac{delta \: L}{2 \sqrt{L} } \: + \frac{delta \: L}{V} \\ \\ delta \: T = \sqrt{ \frac{1}{2gL} } \times delta L \: + \frac{delta \: L}{V} \\ \\ 0.01 = \frac{1}{ \sqrt{2 \times 10 \times 20} } \times delta \: L + \frac{delta \: L}{30} \\ \\ 0.01 = delta \: L \: | \frac{1}{20} + \frac{1}{300} | \\ \\ on \: calcutating \: we \: get \\ \\ deta \: l \: = 0.185 \\ \\ \frac{delta \: L}{L} \times 100 = \frac{0.185}{20} \times 100 = 1\%$
