Answer: 6m
Explanation: 6 is more than 3 and their both being measured by m
 
        
             
        
        
        
We can use the equation for Newton's Law of Gravitation
Fg = (Gm₁m₂)/r²
Where gravitational constant = G = 6.674 x 10⁻¹¹ N · m²/kg²
mass m₁ = 0.145 kg
mass m₂ = 6.8 kg
distance between centers of masses = r = 0.5 m
Substitute these values into... 
Fg = (Gm₁m₂)/r²
Fg = ((6.674 x 10⁻¹¹)(0.145)(6.8)) / (0.5)²
Fg = 2.63 x 10⁻¹⁰ N 
Therefore, your answer should be <span>2.6 × 10–10</span>
        
                    
             
        
        
        
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:
The potential energy (Ep) = 4500 J
Ep = m. g. h
=> m = Ep/(g.h)
m = 4500/(10×10)
 = 4500/100
 = 45
so, the mass = 45 kgs
