Duas partículas eletrizadas com cargas iguais a +25uC estão colocadas a 1,0m uma da outra, no vácuo, onde a constante eletrostática vale 9.10^9 unidades do Sistema Internacional. Não havendo influência de outras cargas, determine:
a) a intensidade do campo eletrostático que cada carga cria no ponto P, situado a meia distancia entre elas;
b) a forca resultante que age numa carga de prova de +2,0uC colocada em P.
