Physics
A ball of radius R and mass m is magically put inside a thin shell of the same mass and radius 2R. The system is at rest on a horizontal frictionless surface initially. When the ball is, again magically, released inside the shell, it sloshes around in the shell and eventually stops at the bottom of the shell. How far does the shell move from its initial contact point with the surface

Explanation:
From the question we are told that mass
Thin layer radius![= 2R](/tpl/images/1009/1453/c276d.png)
Generally the expression for ths solution is given as
Xcm =(m*0 =m(-2R))/2m =-mR/(2m)=-R/2
the center of mass will not move at initial state
Considering the center of mass of both bodies
Therefore the enclosing layer moves

Explanation:
Thickness of the glass plate 2.50mm = 2.50 × 10⁻³m
refractive index of the glass = 1.65
wavelength of the light in vaccum = 600nm
distance between source and screen = 1.35cm = 1.35 × 10⁻²m
wavelength of light in the medium
λ = 600 × 10⁻⁹ / 1.65
λ = 3.6364 × 10⁻⁷
number of wavelength in glass
Distance travel by light in air
D = d - t
D = 1.35 × 10⁻² - 2.50 × 10⁻³
D = 0.011m
Thus, the number of wavelength
Total number of wavelength is
