(1) Dervive an expression for the maximum speed of v of electron in terms of V,me, and e.
(2) The electron is replaced with a proton that starts from rest at the positive plate and travels toward the negative plate. Compare the maximum speed of the protons to the maximum speed of the electron in question 82 and give evidence to support your answer.
(3) according to Ohm's law an ohm is equivalent to a volt per ampere. The ohm can be expressed in terms of the fundamental units kilogram, meter,second, and ampere. Show 1 V/A = 1 kg.m^3/A^2.s^3
(4) Derive an expression for the radius of a conductor in terms of the length, resistance, and resistivity.
Please someone help me with this thank you:)
