A Particle with Charge 2 $\degree$ C Charge Is Placed at the Origin, an Identical Particle

A particle with charge 2 $\degree$ C charge is placed at the origin, an identical particle, with the same charge, is placed 2 m from the origin on the x axis, and a third identical particle, with the same charge, is placed 2 m from the origin on the y axis. The magnitude of the force on the particle at the origin is:

A) 9.0 *10^-3 N
B) 6.4 *10^-3 N
C) 1.3 *10^-2 N
D) 1.8 *10^-2 N
E) 3.6 * 10^-2 N
