Here is the answer!!!!!!!
Gravity increases as mass increases.
Gravity decreases when distance decreases
I hope I help.
Answer:
(A) 
Explanation:
Given:
Charge of one particle (q₁) = -0.0050 C
Charge of another particle (q₂) = 0.0050 C
Separation between them (d) = 0.025 m
We know that, from Coulomb's law, electric force acting between two charged particles is given as:

Plug in the given values and solve for electric force,
. This gives,

Therefore, option (A) is correct. Negative sign implies that the nature of electric force is attraction.
The electron was discovered by researchers working with cathode ray tubes.
The answer would be (A) Protons
