A charge of 50-$\mu$C is placed on the y axis at y = 3.0 cm and a 77-$\mu$C charge is placed on the x axis at x = 4.0 cm.If both charges are held fixed, what is the magnitude of the initial acceleration of an electron released from rest at the origin?
A)1.2 *1020 m/s2
B)1.5 *1020 m/s2
C)1.0* 1020 m/s2
D)1.8 * 1020 m/s2
E)2.0 *1020 m/s2

The forces due to each charge on the electron are calculated using Coulomb's law. The net force is the vector sum of these forces, and the acceleration is found using F=ma, where m is the mass of the electron.
