A particle having mass m and charge \[(-q)\] moves along an ellipse around a fixed charge Q such that its maximum and minimum distance from the fixed charge are \[{{r}_{1}}\] and \[{{r}_{2}}\]respectively. Show that the angular momentum L of this particle about Q is \[a\times {{10}^{4}}Ns\], then find a. \[(Q=2C,\text{ }q=1C,\,\,{{r}_{1}}=3m,\,\,{{r}_{2}}=1m,\text{ }m=0.3kg)\]
