Force = mass * acceleration
15 = 2.1 * a
a = 15/2.1 = 7.143 m/s^2
<span>In Coulomb's law, however, the
magnitude and sign of the electric force are determined by the electric
charge, rather than the mass, of an object. ... Thus, two negative
charges repel one another, while a positive charge attracts a negative
charge. The attraction or repulsion acts along the line between the two charges</span>
