s in your circuits? Draw those circuits
1 answer:
Answer:
5
Explanation:
Let there are three capacitances, C1, C2, and C3.
Combination I:
All the three are connected in series combination.
Combination II:
All the three are connected in parallel combination.
Combination III:
C1, C2 are in parallel and then C3 in series.
Combination IV:
C1, C3 are in parallel and then C2 in series.
Combination V:
C3, C2 are in parallel and then C1 in series.

Answer:
t = 2.58*10^-6 s
Explanation:
For a nonconducting sphere you have that the value of the electric field, depends of the region:
k: Coulomb's constant = 8.98*10^9 Nm^2/C^2
R: radius of the sphere = 10.0/2 = 5.0cm=0.005m
In this case you can assume that the proton is in the region for r > R. Furthermore you use the secon Newton law in order to find the acceleration of the proton produced by the force:
Due to the proton is just outside the surface you can use r=R and calculate the acceleration. Also, you take into account the charge density of the sphere in order to compute the total charge:
with this values of a you can use the following formula:
hence, the time that the proton takes to reach a speed of 2550km is 2.58*10^-6 s
