Question

СРОЧНО. 25 БАЛЛОВ .определите заряд частицы массой 3 мг находящийся в равновесии в однородном электрическом поле напряженностью 0,6 кН/Кл

Answer 1

E=0.6*10^3 Н/Кл     m=3*10^-6 кг   g=10 м/с2   q=?

Сила тяжести уравновешивается силой электрического поля.

m*g=q*E      q=m*g/E=3*10^-6*10/0.6*10^3=50*10^-9 Кл  (50 нКл)

Answer 2

Determining the Charge of the Particle

To determine the charge of the particle, we can use the formula for the force experienced by a charged particle in an electric field when it is in equilibrium:

F = qE

Where: - F is the force experienced by the particle - q is the charge of the particle - E is the electric field strength

Given: - Mass of the particle = 3 mg - Electric field strength = 0.6 kN/C

First, let's convert the mass of the particle from milligrams to kilograms: 1 mg = 1×10^-6 kg

So, the mass of the particle in kilograms is: 3 mg = 3×10^-6 kg

Now, we can use the formula to solve for the charge of the particle:

q = F / E

Where: - F is the force experienced by the particle, which can be calculated using Newton's second law: F = ma (force = mass × acceleration)

Given: - Mass of the particle = 3×10^-6 kg - Electric field strength = 0.6 kN/C

Let's calculate the force experienced by the particle using the formula F = ma and then use it to find the charge of the particle.
