Question

Two plates separated by a distance d = 18.8 mm are charged to a potential difference V = 7.25 V. A constant force F = 6.81 N pushes a -8.30 mC charge from the positively charged plate to the negatively charged plate. Calculate the change in the kinetic energy ?K, potential energy ?U, and total energy ?E of the charge as it travels from one plate to the other. Assume the initial speed of the charge is 0. ?K = 0.0652 J ?U = 0.0627 J ?E = 0.1291 J

Step 1

The electric field is given by the formula E = V/d, where V is the potential difference and d is the distance between the plates. Plugging in the given values, we have E = 7.25 V / 18.8 mm. Show more…

Two plates separated by a distance d = 18.8 mm are charged to a potential difference V = 7.25 V. A constant force F = 6.81 N pushes a -8.30 mC charge from the positively charged plate to the negatively charged plate. Calculate the change in the kinetic energy ΔK, potential energy ΔU, and total energy ΔE of the charge as it travels from one plate to the other. Assume the initial speed of the charge is 0.
