Problem 11-71 Grav & Elec Potential - Part 2 - B
A particular proton in space is subjected to two fields: a gravitational field (\(1.30 \times 10^5\; N/kg\) toward planet \(X\)), and an electric field (\(2.47 \times 10^{-4} \; N/C\) away from planet \(X\)).
(a) If the proton is released from rest, in which direction will it move?
(b) After moving \(1.50 \;m\), what will be its speed? Use energy methods and assume uniform fields.
Accumulated Solution
Correct.
Before continuing, calculate \(F_E\) and \(F_g\). The mass of the proton is \(1.673 \times 10^{-27} \; kg\) and the charge on a proton is \(1.602 \times 10^{-19} \; C\).
