Through what potential difference must an electron (starting from rest) be accelerated if it is to reach a speed of 3.0x10^7 m/s?
Added by David R.
Step 1
- The speed of the electron, v = 3.0 x 10^7 m/s. - The charge of an electron, e = 1.6 x 10^-19 C. - The mass of an electron, m = 9.11 x 10^-31 kg. - The initial speed of the electron is 0 m/s (since it starts from rest). - We need to find the potential Show more…

Through what potential difference must an electron be accelerated, starting from rest, to acquire a speed of $0.99 c ?$
An electron is accelerated from rest through a potential difference ΔV. If the electron reaches a speed of 7.10 10^6 m/s, what is the potential difference? Be sure to include the correct sign.
