139983 A student measures the time period of 100 oscillations of a simple pendulum four times. The data set is \(90 \mathrm{~s}, 91 \mathrm{~s}, 92 \mathrm{~s}\) and \(95 \mathrm{~s}\). If the minimum division in the measuring clock is \(1 \mathrm{~s}\), then the reported mean time should be

1 \((92 \pm 2) \mathrm{s}\)
2 \((92 \pm 5) \mathrm{s}\)
3 \((92 \pm 1.8) \mathrm{s}\)
4 \((92 \pm 3) \mathrm{s}\)

139984 In a slide calliper, \((m+1)\) number of vernier divisions is equal to \(m\) number of smallest main scale divisions. If \(d\) unit is the magnitude of the smallest main scale division, then the magnitude of the vernier constant is

1 \(\mathrm{d} /(\mathrm{m}+1)\) unit
2 \(\mathrm{d} / \mathrm{m}\) unit
3 \(\mathrm{md} /(\mathrm{m}+1)\) unit
4 \((\mathrm{m}+1) \mathrm{d} / \mathrm{m}\) unit
