A student performs experiment with simple pendulum and measures time for 10 vibrations. If he measures the time for 50 vibrations, the error in the measurements of time period will be reduced by a factor of
1 \(5\)
2 \(10\)
3 \(20\)
4 \(50\)
Explanation:
Error in measurement remains the same. Hence, when time is measured for 50 vibrations, instead of 10 vibrations, the relative error will reduce from \(\Delta t/10\) to \(\Delta t/50\), i.e., it will reduce by a factor of 5.

Measure of two quantities along with the precision of respective measuring instrument is \(A = 2.5m{s^{ - 1}} \pm 0.5m{s^{ - 1}},\) \(B = 0.1s \pm 0.01s.\) The value of \(AB\) will be
