A particle with a charge of 7.80 nc is in a uniform electric field directed to the left. another force, in addition to the electric force, acts on the particle so that when it is released from rest, it moves to the right. after it has moved a distance of 7.50 cm , the additional force has done an amount of work equal to 7.10×10−5 j and the particle has kinetic energy equal to 3.55×10−5 j .
