Physics Grade 12 HELP!!!! Electricity Unit
I have attached the question paper with this post
v=2 x 10 ^ 5 m/s
Volatage=250 or 500?
Constants Given:
Coulombs constant = 9 x 10^9
Charge of proton/electron = 1.6 x 10^19/1.6 x 10^19
Proton rest mass 1.673 x 10^27 kg
Electron Rest Mass= 9.11 x 10^31 kg
EK=EE?
Or Ek+W=0
Ek=0.5mv^2
=0.5*(1.673 x 10^27) * (2x10^5)^2
=3.346 x 10^17 J
=3.346 x 10^17 J + W=0
W=3.346 x 10^17 J
