Complete question is;
Which of the following object would take you the greatest amount of force to accelerate.
A) a soccer ball with a mass of 0.5 kg
B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg
D) a car with a mass of 5,000 kg,
Answer:
D) a car with a mass of 5,000 kg
Explanation:
Formula for force is;
F = ma
Where;
F is force
m is mass
a is acceleration
Now, Force is directly proportional to the acceleration and mass.
Thus, the higher the mass, the greater the force.
Thus, the object that will require the most force is the one that has the highest mass.
Looking at the options, the one with the highest mass is option D.
The radius of the anion is 7.413 nm
<h3>How to calculate the force of attraction between charges</h3>
The force of attraction (F) is given by the formula:
- F = (1/4π∈r²)(Zc*e)(Za*e)
where:
∈ = permittivity of free space = 8.85*10⁻¹⁵ F/m
Zc = charge on the cation = +2
Zc = charge on the anion = -2
e = charge on an electron = 1.602 * 10⁻¹⁹ C
r = interionic distance
r = rc + ra
where rc and ra are the radius of the cation and anion respectively
F = 1.64 * 10⁻⁸ N
Therefore based on the equation of force of attraction:
1.64 *10⁻⁸ = [1/4π(8.85*10⁻¹⁵)r²](2 * 1.602*10⁻¹⁹)²
r² = 5.63 * 10⁻¹⁷
r = 7.50 nm
Since r = rc + ra
where rc = 0.087 nm
thus, ra = r - rc = 7.50 - 0.087
ra = 7.413 nm
Therefore, the radius of the anion is 7.413 nm
