Problem

In a pendulum experiment the length

L

is measured with a positive error of

1\%

, while the error in the measurement of the time period

T

is negligible. The percentage error in the calculated value of

g

will be (a)

0.5\% \text{ increase}

(b)

2\% \text{ increase}

(c)

1\% \text{ increase}

(d)

1\% \text{ decrease}
