I am stuck on this module 6 electromagnetism question:
'Two charged parallel plates have a potential difference of 35.0 V.
How far apart must these two plates be so that a point charge of -4.0*10^-8 C with a mass of 2.5*10^-6 kg will be exactly suspended against gravity?"
I dont have a...
For an experimental report / depth study (with the theme of 'Analyse electric and magnetic interactions due to charged particles, currents, and/or fields.'), I would like to make an experiment that involves the motor with a gear box as seen in the attatcehd image (Single Motor 4 Speed...
I will be conducting an experiment and writing a report on it (depth study) based on the theme of: 'Analyse electric and magnetic interactions due to charged particles, currents, and/or fields'. This experiment must be 'engaging' / creative (because otherwise, I lose marks in the...
A question popped up in a physics textbook and I would just like to clarify my answer:
a) My answer: Potential difference is positive so ΔV = ΔU/q
and since potential difference is positive so must be ΔU.
ΔU = q*ΔV = (-1.602 * 10^-19)(100)
= -1.602 * 10^-17
ΔU = -ΔKe
-1.602 * 10^-17 =...
