Answer 2

The electric field intensity of the Earth's atmosphere is given as 130 V/m and directed downwards. We need to find the acceleration experienced by a dust particle with a mass of 10^-7 g and a positive charge of 1.6 x 10^-17 C.

To find the acceleration, we can use the equation F = qE, where F is the force experienced by the particle, q is the charge of the particle, and E is the electric field intensity.

The force experienced by the particle can be calculated using the equation F = ma, where m is the mass of the particle and a is the acceleration.

By equating the two equations, we can find the acceleration:

F = qE ma = qE a = (qE) / m

Substituting the given values:

q = 1.6 x 10^-17 C E = 130 V/m m = 10^-7 g = 10^-10 kg

a = (1.6 x 10^-17 C * 130 V/m) / 10^-10 kg

Calculating this expression gives us the value of the acceleration.
