What is the strength of an electric field that will balance the weight of a 1.0 g plastic sphere that has been charged to −3.0nc?

Explanation:

In order to balance the weight of the sphere, the electric force must be equal in magnitude to the weight of the sphere:

where

is the charge of the sphere (we can ignore the sign, since we are only interested in the magnitude of the force

E is the strength of the electric field

m = 1.0 g = 0.001 kg is the mass of the sphere

g = 9.81 m/s^2 is the gravitational acceleration

Solving the equation for E, we find the strength of the electric field:

vapour or gas assuming atmospheriv pressure

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
