Question
moving a charge from point a,where the potential is 300v, to point b,where the potential is 150v takes 4.5x 10-4 J ofwork. What is the value of the charge?

W=q•Δφ
q= W/Δφ=4.5•10⁻⁴/(300-150)= 3•10⁻⁶C
Since this motion takes energy
q= - 3•10⁻⁶C
q= W/Δφ=4.5•10⁻⁴/(300-150)= 3•10⁻⁶C
Since this motion takes energy
q= - 3•10⁻⁶C
