Answer:
A) for leftmost point the coordinate is -0.28m that means it should be 0.28m towards the right.
B) for rightmost case the coordinate is 0.28m which is where komila should sit. 
Explanation:
Detailed calculation and explanation is shown in the image below 
 
        
             
        
        
        
The physical model of the sun's interior has been confirmed by observations of neutrino and seismic vibrations.
<u>Explanation:</u>
Sun's interior is composed of very high temperature and solar flares. So it is very difficult to understand the interior of the sun. But by using the vibrations of neutrino and seismic waves emitted by the solar waves, the physical model can be assumed.
As the interior of the sun performs continuous chain of hydrogen cycle. So the continuous emission of energy from the chain reaction releases neutrino. So these vibrations in neutrino and seismic vibrations, the physical model can be assumed easily.
 
        
             
        
        
        
Answer: 250n
Explanation: 
The formula for gravitational force is: F = (gMm)/r^2
There are two factors at play here:
1) The mass of the planet 'M'
2) The radius 'r'
We can ignore the small M and the g, they are constants that do not alter the outcome of this question. 
You can see that both M and r are double that of earth. So lets say earth has M=1 and r=1. Then, new planet would have M=2 and r=2. Let's sub these two sets into the equation: 
Earth. F =  M/r^2 = 1/1 
New planet. F = M/r^2 = 2/4 = 1/2
So you can see that the force on the new planet is half of that felt on Earth. 
The question tells us that the force on earth is 500n for this person, so then on the new planet it would be half! So, 250n!
