11-71. A particular proton in space is subjected to two fields: a
gravitational field (1.30X105 N/kg toward planet X),
an electric field (2.47X10-4 N/C away from planet X).
(a) If the proton is released from rest, in which direction will
(b) After moving 1.50 m, what will be its speed? Use energy
and assume uniform fields.
No. You have the variables of electric field
and gravitational field confused.
