Humid air breaks down electrically when its molecules become ionized. this happend in an electric field |E|=3*10^6 N/C. In that field, calculate the magnitude of the electric force on an ion with a single positive charge.
..when they say a single positive charge do they mean +1, or +e (e=1.6*10^-19)...and would I just put |E| and q ( +1 or +e) into the following equation... F=qE ... or is it more complicated...?
Yeah you just use F=qE, so you just multiply E by e
To calculate the magnitude of the electric force on an ion in an electric field, you can use the equation F = qE, where F is the magnitude of the electric force, q is the charge of the ion, and E is the magnitude of the electric field.
In this case, since the ion is mentioned to have a single positive charge, it means that the charge is +1. Therefore, you can consider q = +1 in the equation.
Given that the magnitude of the electric field |E| is 3 * 10^6 N/C, you can substitute these values into the equation and solve for F:
F = qE
F = (+1) * (3 * 10^6 N/C)
F = 3 * 10^6 N
So, the magnitude of the electric force on the ion with a single positive charge in an electric field with |E| = 3 * 10^6 N/C is 3 * 10^6 N.
