A) \[\alpha >\,\beta >\gamma \]
B) \[\alpha >\,\gamma >\beta \]
C) \[\gamma >\,\alpha >\beta \]
D) \[\gamma >\beta >\alpha \]
Correct Answer: D
Solution :
The order of velocity of a, P and y rays is \[\underset{(3\times {{10}^{8}}m/s)}{\mathop{\gamma }}\,\,\,\,>\,\,\,\,\,\underset{\begin{smallmatrix} (2.36\,\times \,{{10}^{8}}\,m/s \\ to\,2.83\,\times \,{{10}^{8}}\,m/s) \end{smallmatrix}}{\mathop{\beta }}\,>\underset{(2\times {{10}^{7}}\,m/s)}{\mathop{\alpha }}\,\]
