Answer:
a)
b) parallel to the earth surface.
- In this case according to the Fleming's left hand rule the direction of movement of bee must be in a direction parallel to the earth surface and perpendicular to the electric field at the same time.
Explanation:
Given:
mass of the bee,
charge acquired by the bee,
a.
Electrical field near the earth surface,
Now the electric force on the bee:
we know:
The weight of the bee:
Therefore the ratio :
b.
The condition for the bee to hang is its weight must get balanced by the electric force acing equally in the opposite direction.
So,
parallel to the earth surface.
- In this case according to the Fleming's left hand rule the direction of movement of bee must be in a direction parallel to the earth surface and perpendicular to the electric field at the same time.
