Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 times 10^7 n/c. what is the magnitude of the force on a calcium ion with charge +e? express your answer using two significant figures.

Explanation:

The electric force on a charged particle is given by

where

q is the charge of the particle

E is the strength of the electric field

In this problem, we have

is the electric field strength

is the charge of the calcium ion

Therefore, the electric force exerted on the calcium ion is

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
