While measuring the length of the rod by vernier callipers, the reading on the main scale is 6.4 cm and the eight divisions on vernier is in line with marking on the main scale division. If the least count of callipers is 0.01 and zero error - 0.04 cm, the length of the rod is ________

Pressure P varies as $P=\frac{\alpha}{\beta}exp(-\frac{\alpha x}{k_{B}T})$ where x denotes the distance, $k_{B}$ is the Boltzmann's constant, T is the absolute temperature and $\alpha$ and $\beta$ are constant. The dimension of $\beta$ is ________

If two resistors of resistances $R_{1}=(4\pm0.5)\Omega$ and $R_{2}=(16\pm0.5)\Omega$ are connected in series. The equivalent resistance with the limits of percentage error is ________
