No the speed does not depend on its mass, yes to the second question and yes to the third
Answer:
q= 1.9*10⁻¹⁶ C
Explanation:
To solve this problem we apply Coulomb's law:
Two point charges (q1, q2) separated by a distance (d) exert a mutual force (F) whose magnitude is determined by the following formula:
F=K*q₁*q₂/d² Formula (1)
F: Electric force in Newtons (N)
K : Coulomb constant in N*m²/C²
q₁,q₂:Charges in Coulombs (C)
d: distance between the charges in meters(m)
Data
F=2.37*10⁻³ N
K=8.99*10⁹N*m²/C²
q₁ = q₂=q
d= 3.7*10⁻¹⁰ m
Problem development
We replace data in the formula (1) to calculate q:
F=K*q₁*q₂/d²
F= K*q*q*/d²
F*d²= K*q²
F*d²/K= q²
q= 1.9*10⁻¹⁶ C
For example if an iron is heated it will get longer and fatter and its density will decrease. This happens because the mass of a rod stays the same but its volume increases....... A few substances behave differently when heated or cooled. Water is one such substance
