The cockroach periplaneta americana can detect a static electric field of magnitude 8.50 kn/c using their long antennae. if the excess static charge on a cockroach is modeled as point charges located at the end of each antenna, what magnitude of charge would each antenna possess in order for each antennae to experience a force of magnitude 5.50 μn from the external electric field? calculate in units of nanocoulombs (nc) .

0.647 nC

Explanation:

The force experienced by a charge due to the presence of an electric field is given by

where

q is the charge

E is the magnitude of the electric field

In this problem, each antenna is modelled as it was a single point charge, experiencing a force of

Therefore, if the electric field magnitude is

Then the charge on each antenna would be

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

statement #3 on andre"s list is false.
