Answer:
Example A will appear green, while Example B will appear greenish-blue.
Explanation:
The color of an object depend on which part of the visible light it reflects towards the observer. Visible light is made up of seven colors: Violet, Indigo, Blue, Green, Yellow, Orange, and Red (VIBGYOR). If all the colors will be reflected object will appear white. If all the colors are absorbed the object appears black. In example A, only green color is being reflected so it will appear <em>Green</em>.
In example B, green and blue are being reflected so the object will appear a mix of green and blue. This color is cyan (greenish blue).
Answer:
The ratio of electric force to the gravitational force is 
Explanation:
It is given that,
Distance between electron and proton, 
Electric force is given by :
Gravitational force is given by :
Where
is mass of electron, 
is mass of proton, 
is charge on electron, 
is charge on proton, 
So, the ratio of electric force to the gravitational force is . Hence, this is the required solution.
