Answer 1

your question is -> what is the fractional error in g calculated from T = 2π√{l/g}

what is the fractional error in g calculated from T = 2π√{l/g}given, that fractional errors in T and l are x and y respectively.

solution : T = 2π√{l/g}

or, T² = 4π²l/g

or, g = 4π²l/T²

so, formula of fractional error in g is defined as , ∆g/g = ∆l/l + 2∆T/T

or, fractional error in g = fractional error in l + 2 × fractional error in T

given, fractional error in T = x

fractional error in l = y

so, fractional error in g = y + 2x

Answer 2

Answer:

The correct answer is 2x + y
