Answer:
By the principle of corona discharge.
Explanation:
The charge on each ball will decreases over time due to the electrical discharge in air.
According to the principle of corona discharge, when the curvature is small, the discharge of the charge takes placed form the pointed ends.
At high altitudes, the air pressure is lower and it is more difficult for us to breathe because we cannot take in enough oxygen.
Answer:
If there is no horizontal component to the force then it is just 0N
Explanation:
