A) 2
B) 1/2
C) 4
D) None of these
Correct Answer: A
Solution :
[a] Using formula of spherical surface taking 'B' as object \[\frac{{{\mu }_{2}}}{\infty }-\frac{{{\mu }_{1}}}{(-2R)}=\frac{{{\mu }_{2}}-{{\mu }_{1}}}{-R}\] (R being the radius of the curved surface) \[\Rightarrow \] \[\frac{{{\mu }_{1}}}{{{\mu }_{2}}}=2\]You need to login to perform this action.
