1.	The figure ,shows a transparent sphere of radius`R`and refractive index`mu`.An object `O`is placed at a distance `x` from the pole of the first surface so that a real image is formed at the pole of the exactly opposite surface. If `x=oo`,then the value of `mu` isA. `1.5`B. `2`C. `3`D. None of these
Answer» Correct Answer - B `(mu_(2))/(v)-(mu_(1))/(u)=(mu_(2)-mu_(1))/(R ) rArr (u)/(2R)-(1)/(oo)=(mu-1)/(R ) rArr (mu)/(2)=mu-1` `(mu)/(2)=1 rArr mu=2`
