A) Describe what the Zeroth Law of Thermodynamics is in your own words. Also, draw a scenario that verifies the Law is accurate.
B) State the other Laws of Thermodynamics in your own words.
Two particles are fixed to an x axis: particle 1 of charge q1 = +2.1 10-8 C at x = 20 cm and particle 2 of charge q2 = -4.00q1 at x = 70 cm. At what coordinate on the axis is the net electric field produced by particles equal to zero.
A point charge with charge q1 is held stationary at the origin. A second point charge q2 with charge moves from the point (x1, 0) to the point (x2,y2 ). How much work is done by the electrostatic force on the moving point charge? Express your answ..
