Question

Заряженные шарики, находящиеся на расстоянии 1.3 м друг от друга, отталкиваются с силой 1.4 Н. Суммарный заряд шариков равен 40 мкКл. Найдите заряд каждого шарика.

Answer 1

$F=k \frac{q_1q_2}{r^2}$
$1,4=9*10^9\frac{q_1*q_2}{1,3^2}$
$q_1*q_2= \frac{1,4*1,3^2}{9*10^9}=0.26*10^{-9}$
$q_1+q_2=4*10^{-5}$
$q^2-4*10^{-5}q+0.26*10^{-9}=0$
$q_1=3.2*10^{-5} KL$
$q_2=q-q_1=40*10^{-6}-3.2*10^{-5}=0.8*10^{-5}KL$

Answer 2

Calculation of the Charge of Each Ball

To find the charge of each ball, we can use the given information about the force between the balls and the total charge of the system.

The force between two charged objects can be calculated using Coulomb's Law, which states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Let's denote the charge of one ball as Q1 and the charge of the other ball as Q2. The distance between the balls is given as 1.3 m, and the force between them is given as 1.4 N.

Using Coulomb's Law, we can write the equation for the force between the balls as:

F = k * (Q1 * Q2) / r^2 Where: - F is the force between the balls (1.4 N) - k is the electrostatic constant (unknown) - Q1 and Q2 are the charges of the balls (unknown) - r is the distance between the balls (1.3 m)

We can rearrange the equation to solve for the product of the charges:

(Q1 * Q2) = (F * r^2) / k Now, we are given that the total charge of the system is 40 μC (microcoulombs). The sum of the charges of the two balls is equal to the total charge:

Q1 + Q2 = 40 μC To find the individual charges of the balls, we can solve these two equations simultaneously.

Unfortunately, the specific value of the electrostatic constant (k) is not provided in the search results. Therefore, we cannot calculate the exact charges of the balls without this information.

However, we can still discuss the general approach to solving this problem and the importance of the electrostatic constant in the calculation.

The electrostatic constant (k) is a fundamental constant in physics and is equal to approximately 8.99 x 10^9 N·m^2/C^2. It determines the strength of the electrostatic force between two charged objects.

Without knowing the value of k, we cannot calculate the exact charges of the balls. However, we can discuss the relationship between the charges and the force.

If the electrostatic constant (k) is known, we can substitute its value into equation and solve for the product of the charges (Q1 * Q2). Then, by substituting this value into equation we can find the individual charges of the balls (Q1 and Q2).

In conclusion, without the value of the electrostatic constant (k), we cannot calculate the exact charges of the balls. However, we have discussed the general approach to solving this problem and the importance of the electrostatic constant in the calculation.
