11-71. A particular proton in space is subjected to two fields: a
gravitational field (1.30X105 N/kg toward planet X),
and
an electric field (2.47X10-4 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.
