To determine

(a)

To determine: To write the Newton’s first law (no net force applied) and expression for the terminal speed of micron sized soot particle under the influence of the downward electric field of earth.

To determine

(b)

To determine: The terminal speed of $1.0\mu m$ diameter particle (in mm/s) in the absence of electric field of earth.

To determine

(c)

To determine: The terminal speed of $1.0\mu \text{m}$ diameter particle (in mm/s) in the presence of electric field ($150\text{N/C}$) of earth.
