Two point charges are separated by a distance of 10.0 cm. one has a charge of -25 μc and the other +50 μc. (a) determine the direction and magnitude of the electric field at a point p between the two charges that is 2.0 cm from the negative charge. (b) if an electron (mass = 9.11 x 10-31 kg) is placed at rest at p and then released, what will be its initial acceleration (direction and magnitude)?
