# Problem 11-71 Grav & Elec Potential - Part 2 - 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.

Accumulated Solution

No. You have the variables of electric field and gravitational field confused.

Try again.
