Calculation of the Acceleration of the Charged Dust Particle

To calculate the acceleration of the charged dust particle in the given scenario, we can use the formula for the force experienced by a charged particle in an electric field:

F = qE

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

In this case, the charge of the dust particle is given as 10^-12 C and the electric field strength is given as 200 V/m. We need to find the acceleration, which can be calculated using Newton's second law:

F = ma

Where: - F is the force experienced by the particle - m is the mass of the particle - a is the acceleration of the particle

Since the mass of the dust particle is given as 10^-6 kg, we can substitute the values into the equations to find the acceleration.

Step 1: Calculate the force experienced by the particle using the formula F = qE.

F = (10^-12 C) * (200 V/m)

F = 2 * 10^-10 N

Step 2: Substitute the force into Newton's second law equation F = ma to find the acceleration.

2 * 10^-10 N = (10^-6 kg) * a

a = (2 * 10^-10 N) / (10^-6 kg)

a = 2 * 10^-4 m/s^2

Therefore, the dust particle moves with an acceleration of 2 * 10^-4 m/s^2 in the given electric field.
