A) 5.2 cm
B) 7.2 cm
C) 4.2 cm
D) 3.2 cm
Correct Answer: A
Solution :
By using \[\frac{{{\mu }_{2}}}{v}-\frac{{{\mu }_{1}}}{u}=\frac{{{\mu }_{2}}-{{\mu }_{1}}}{R}\] where \[{{\mu }_{1}}\,=\,\,\frac{4}{3},\,\,{{\mu }_{2}}=1,\,\,u=-\,6\,cm,\,\,\nu =?\] On putting values \[\operatorname{v} = -5.2 cm\]You need to login to perform this action.
