A) \[\alpha =1 cm,\,\,\beta = 1 cm\]
B) \[\alpha =2 cm,\,\,\beta = 1 cm\]
C) \[\alpha =1 cm,\,\,\beta = 2 cm\]
D) none of these
Correct Answer: A
Solution :
\[\alpha \,\,=\,\,\frac{{{R}_{2}}{{l}_{1}}-{{R}_{1}}{{l}_{2}}}{{{R}_{1}}-{{R}_{2}}}\] \[=\,\,\frac{(200)(33)-(100)(67)}{100-200}\,\,=\,\,\,1\,\,cm\] \[\beta \,\,=\,\frac{{{R}_{1}}{{l}_{1}}-{{R}_{2}}{{l}_{2}}}{{{R}_{1}}-{{R}_{2}}}-100\] \[=\,\,\frac{(100)-(200)(67)}{100-200}\,\,\,-\,\,100=1\,cm\]You need to login to perform this action.
