Answer:
F = 3.6 x 10⁻²⁴ N
Explanation:
The force of attraction or repulsion between two charges is given by the Coulomb's Law. Coulomb's Law states that:
F = kq₁q₂/r²
where,
F = Electric Force between electrons = ?
k = Coulomb's Constant = 9 x 10⁹ N.m²/C²
q₁ = q₂ = Charge on electron = 1.6 x 10⁻¹⁹ C
r = distance between electrons = 0.8 cm = 0.008 m
Therefore,
F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(0.008 m)²
<u>F = 3.6 x 10⁻²⁴ N</u>
Answer: velocity
Explanation: Hope this helps :)
Answer:
Kinetic friction is related to the normal force N by f k = μ k N f k = μ k N ; thus, we can find the coefficient of kinetic friction if we can find the normal force on the skier
