Equal masses of two samples of charcoal `A` and `B` are burnt separately and the resulting carbon dioxide is collected in two vessels. The radioacitivity of `.^(14)C` is measured for both the gas samples. The gas from the charcoal `A` gives `1400` counts per week. Find teh age difference between the two samples.
(Half-life `.^(14)C = 5730yr`)

Answer
