Answer:
(Fuerza de repulsión/Repulsive force)
Explanation:
La fuerza ejercida entre las dos partículas se calcula por la Ley de Coulomb (The force exerted between the two particles is determined by Coulomb's Law):
Donde (Where):
- Constante electrostática, medido en
(Electrostatic constant, measured in
).
,
- Magnitudes de las cargas de cada partícula, medidos en Coulombs. (Magnitudes of charges from each particle, measured in Coulombs).
- Distancia entre las partículas, medida en metros.
La fuerza electrostática es (Electrostatic force is):
Dado que las partículas tienen el mismo signo de carga, la fuerza es de repulsión. (Given that both particles have the same charge sign, the force is of repulsive nature)
Answer:
The Ferris wheel's tangential (linear) velocity if the net centripetal force on the woman is 115 N is <u>3.92 m/s</u>.
Explanation:
Let's use <u>Newton's 2nd Law</u> to help solve this problem.
- F = ma
The force acting on the Ferris wheel is the centripetal force, given in the problem: .
The mass "m" is the <u>sum</u> of the man and woman's masses: .
The acceleration is the centripetal acceleration of the Ferris wheel: .
Let's write an equation and solve for "v", the tangential (linear) acceleration.
The Ferris wheel's tangential velocity is 3.92 m/s.
