It makes the data thet they collect more reliable so if they need the data again, they have already tested it a few times so therefor they know that it is right.

Answer:
Explanation:
Coulomb’s law is given as;
where;
F is the electric force between q₁ and q₂
k is the coulomb’s constant = 9 x 10⁹ Nm²/C²
r is the distance between the two charges
q₁ and q₂ are the two charges
Therefore, the coulomb’s law is given as
Given:
mass of object, m = 25 kg
accelaration of the object, a = 2 m/
accelaration when force acts upon another object, a' = 5 m/
Explanation:
To find the mass m' of the object:
Given that:
mass ∝
Also, from Newton's second law of motion:
F = ma (1)
where,
F = force
Now, using eqn (1)
F =
F = = 50 N
Now, since constant force acts on both the objects:
Therefore, F' = = F
50 =
m' = 10 kg
Therefore, the mass, m' of the second object is 10 kg
