Na figura acima, a linha pontilhada mostra a trajetória de uma partícula de carga -q = -3 C que percorre 6m metros, ao se deslocar do ponto A, onde estava em repouso, até o ponto B, onde foi conduzida novamente ao repouso. Nessa região do espaço, há um campo elétrico conservativo, cujas superfícies equipotenciais estão representadas na figura. Sabe-se que, ao longo desse deslocamento da partícula, atuam somente duas forças sobre ela, onde uma delas é a força externa Fext. Sendo assim, determine o trabalho, em quilojoules, realizado pela força Fext no deslocamento da partícula do ponto A até o ponto B.
