1. The problem statement, all variables and given/known data A particle of mass 3x 10^-12kg carrying a charge of +4.0x 10^-14C is released at the upper plate of a pair of horizontal parallel conducting plates placed in a vacuum. 2. Relevant equations (1) Calculate the net force on the particle: I added the electric force VQ/d and the weight W=mg (2) Calculate the KE of the particle when it reaches the lower plate: work done =gain in KE= Fd (3) Explain the effect on force and the KE if the separation of the plates is increased. (this i'm not sure about) 3. The attempt at a solution I'm thinking that since F= VQ/d if the distance increases then the force would decrease. I could be wrong. Since, the gain in KE is equivalent to the work done =Fd and since F decreases (I assume) then the KE would also decrease. Am I wrong?
