Avoltage of 18 v is applied across the ends of a piece of copper wire 8 em long. the mass of an electron is 9.11 x 10-31 kg and its charge is 1.6 × 10-19 c. what is the magnitude of the electron's acceleration?

m/s²

Explanation:

V = Potential difference between the ends of copper wire = 18 Volts

d = distance between the ends of the wire = 8 cm = 0.08 m

E = Electric field between the ends

Using the equation

V = E d

18 = E (0.08)

E = 225 N/C

m = mass of electron = 9.1 x 10⁻³¹ kg

q = magnitude of charge on electron = 1.6 x 10⁻¹⁹ C

Magnitude of acceleration of electron is given as

m/s²

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
