Answer:
Average net force, F = 15157.15 N
Explanation:
It is given that,
The mass of the car and riders is,
Initial speed of the car, u = 0
Final speed of the car, v = 43.4 m/s
Time, t = 8.59 seconds
We need to find the average net force exerted on the car and riders by the magnets. It can be calculated using second law of motion as :
F = m a
F = 15157.15 N
So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.
Answer:
Datos:
q1 = -50 μC =
q2 = +30 μC =
F = 10 N
a) x si la <em>F = 10N</em>
Aplicando la Ley de Coulomb:
x = =
= 1,162m
b) x si la <em>F = 20 N</em>
x=<em> </em><em> </em>= 0,822m
c)x si la <em>F = 50 N</em>
x = = 0,520m
