The required value of the index of refraction of glass is 1.5.
Given data:
The speed of light in a vacuum is, .
The speed of light in a glass is, .
Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,
n = c / v
Solving as
Thus, we can conclude that the required value of the index of refraction of glass is 1.5.

Answer:
F=2.47*10^{-10} N
Explanation:
The gravitational force is calculated by using
G: Cavendish constant = 6.67*10^{-12}Nm^2/kg^2
r=2.30cm=0.023m
M1=1.4kg
M2=14.0g=0.014kg
By replacing we have
F=2.47*10^{-10} N
hope this helps!!
