Answer:
e.0.11
Explanation:
We are given that
[tex]R_1=R[/tex]
[tex]R_2=3 R[/tex]
We have to find the ratio of the intensity of solar radiation on sphere 2 to that on sphere 1.
Intensity is inversely proportional to square of distance from sun.
[tex]\frac{I_2}{I_1}=\frac{R^2_1}{R^2_2}[/tex]
Using the formula
[tex]\frac{I_2}{I_1}=\frac{(R^2}{(3R)^2}[/tex]
[tex]\frac{I_2}{I_1}=\frac{1}{9}[/tex]
[tex]\frac{I_2}{I_1}=0.11[/tex]
Option e is true.
Answer:
Ratio of intensity of solar radiation on sphere 2 to sphere 1 is 0.11
So option (e) will be correct answer
Explanation:
We have given two identical silver sphere of mass and radius r
Distance of first sphere from sun is R
And distance of second sphere from sun is 3R
We know that intensity of solar radiation is inversely proportional to square of distance from sun
So [tex]\frac{I_2}{I_1}=\frac{R_1^2}{R_2^2}[/tex]
[tex]\frac{I_2}{I_1}=\frac{R^2}{(3R)^2}[/tex]
[tex]\frac{I_2}{I_1}=\frac{1}{9}=0.111[/tex]
So ratio of intensity of solar radiation on sphere 2 to sphere 1 is 0.11
So option (e) will be correct answer
