Question

A 12-V battery is connected to two metallic plates, creating a uniform electric field between them.


a) The separation between the plates is 2.00 cm. Calculate the magnitude of the uniform electric field between them.

b) A positive charge q is released somewhere in between the two plates, it then travels a distance of 1.00 cm. Calculate the potential difference = Vf - Vi between the final and initial positions.

c) Calculate the final velocity of the moving charge at the end of its 1.00 cm
displacement if q = +5.0µC and its mass is m = 1.2 x10^-5 kg

Explanation / Answer

v = ((6.0 * 10-5 J/1.2 * 10-5 kg))1/2 = 2.236 m/s
