Problem 11-71 Grav & Elec Potential - A

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.

No. Is the gravitational force attractive or repulsive?

Choose one.
