Two identical charged particles each having a mass 10g and charge 2 × ...


Given data:
- Mass of each particle, m = 10g = 0.01kg
- Charge of each particle, q = 2 × 10^-7 C
- Coefficient of friction, μ = 0.25

Equilibrium condition:
When the two particles are separated by a distance L and are in equilibrium, the electrostatic force between them will be balanced by the frictional force.

Electrostatic force:
The electrostatic force between the two particles is given by Coulomb's law:
F = k * (q^2) / L^2
where k is the electrostatic constant (9 × 10^9 Nm^2/C^2).

Frictional force:
The frictional force acting on each particle is given by:
f = μ * m * g
where g is the acceleration due to gravity (9.8 m/s^2).

Equilibrium condition:
For equilibrium, the electrostatic force and the frictional force must balance each other:
k * (q^2) / L^2 = μ * m * g

Solving for L:
L = sqrt(k * (q^2) / (μ * m * g))

Substitute the values:
- k = 9 × 10^9 Nm^2/C^2
- q = 2 × 10^-7 C
- m = 0.01kg
- μ = 0.25
- g = 9.8 m/s^2

Calculate:
L = sqrt((9 × 10^9 * (2 × 10^-7)^2) / (0.25 * 0.01 * 9.8))
L = sqrt(36)
L = 6 meters
Therefore, the separation distance between the two particles for them to stay in equilibrium is 6 meters.
