Solution

The correct option is C $C_{1} < C_{2} < C_{3}$
Clearly, $A$ is denser than $B$ and $B$ is denser than $C$ .
$∴ μ_{1} > μ_{2} > μ_{3}$
$∴ C_{1} < C_{2} < C_{3}$ .

Q. Three circles C1, C2 and C3 having diameters 3 cm, 4 cm and 5 cm are intersecting each other such that their diameters form a triangle. If the area common to circles C1 and C2, C2 and C3, C3 and C1 are a, b and c respectively then find the area common to all the three circles.

Let $c_{1} : x^{2} + y^{2} = 1; C_{2} : (x - 10)^{2} + y^{2} = 1 a n d C_{3}; x^{2} + y^{2} - 10 x - 42 y + 457 = 0$ be three circle.A circle C has been drawn to touch circles $C_{1}$ and $C_{2}$ externally and $C_{3}$ internally. Now circles $C_{1}, C_{2}$ and $C_{3}$ start rolling on the circumference of circle C in anticlockwise direction with constant speed. The centroid of the triangle formed by joining the centres of rolling circles $C_{1}, C_{2}$ and $C_{3}$ lies on

A,B, and C are three optical media of respective critical angles C1,C2, and C3. Total internal reflection of light occur from A and B, also from B to C but not from C to A. Then, the correct relation between the critical angles is

The correct option is C C1<C2<C3Clearly, A is denser than B and B is denser than C.∴μ1>μ2>μ3∴C1<C2<C3.
