SUMMARY
The discussion centers on calculating the ratio of the electric force on a honeybee, which has a charge of 18 pC, to its weight. The weight of the bee is determined using the formula W=mg, resulting in a weight of 0.00147 N. The electric force can be calculated using the electric field strength of 100 N/C and the charge, leading to a force of 1.8 x 10-6 N. To achieve suspension in the air, the electric field strength must equal the weight of the bee, requiring a field of approximately 0.00147 N/C directed upward.
