Speed is the secular unit, which means it only measures "how fast it goes."
Velocity is a victory unit, which means it measures "both how fast it goes AND the direction."
Acceleration is the change of velocity over time.

Answer:
1681714.28571 N/C
Yes it could exist
Explanation:
m = Mass of housefly = 12 m
q = Charge = 70 pC
g = Acceleration due to gravity = 9.81 m/s²
E = Electric field
When an object accumulates charge it means that it is gaining electrons making it negatively charged. This is the concept of static electricity.
Here, the electric force and the graviational force will balance each other
1681714.28571 N/C of electric field would be required to levitate
The direction of the electric field would be upwards vertically.
In air the critical value of electric field is which is more than the critical value of electric field in air. So, the electric field can exist.
