Question

В некоторой точке электрического поля на заряд 1 мкКл действует сила 1 Н. какая сила будет действовать на этот же заряд, если напряженность поля увеличивается в 1.5 раза?

Answer 1

Сила и напряженность пропорциональны друг другу, Если напряженность увеличить в 1,5 раза, то и сила соответственно возрастет в 1,5 раза и станет 1,5 Н

Answer 2

Calculation of the Force on the Charge

To calculate the force on a charge in an electric field, we can use the formula:

F = qE

Where: - F is the force on the charge, - q is the magnitude of the charge, and - E is the electric field strength.

In this case, we are given that the charge is 1 μC (1 microcoulomb) and the force acting on it is 1 N (1 newton).

Let's calculate the electric field strength using the given information.

Calculation of the Electric Field Strength

We can rearrange the formula to solve for the electric field strength:

E = F / q

Substituting the given values:

E = 1 N / 1 μC

To simplify the calculation, we need to convert the charge from microcoulombs to coulombs. Since 1 μC is equal to 1 × 10^(-6) C, we have:

E = 1 N / (1 × 10^(-6) C)

Calculating this, we find:

E = 1 × 10^6 N/C

Now, we are asked to determine the force on the same charge when the electric field strength is increased by a factor of 1.5.

Calculation of the New Force

To find the new force, we can use the formula:

F' = qE'

Where: - F' is the new force on the charge, - q is the magnitude of the charge, and - E' is the new electric field strength.

We are given that the electric field strength is increased by a factor of 1.5. Therefore, the new electric field strength is:

E' = 1.5 × E

Substituting the value of E, we have:

E' = 1.5 × (1 × 10^6 N/C)

Calculating this, we find:

E' = 1.5 × 10^6 N/C

Now, we can calculate the new force using the formula:

F' = qE'

Substituting the value of q and E', we have:

F' = (1 × 10^(-6) C) × (1.5 × 10^6 N/C)

Calculating this, we find:

F' = 1.5 N

Therefore, the force on the charge when the electric field strength is increased by a factor of 1.5 is 1.5 N.

Please note that the calculations provided above are based on the given information and the formulas for calculating the force and electric field strength in an electric field.
