2.Suppose an electric field with a magnitude of 2.8 E 4 N/C at a certain location, points due south. If a charge of -4.0 E -6 C is brought to the location, what is the electrostatic force that acts on this charge?
1.Matt forgot to put the fabric softener in the wash. As his socks tumbled in the dryer, they became charged. If a small piece of lint with a charge of +1.25 E -19 C is attracted to the socks by a force of 3.0 E -9 N, what is the magnitude of the electric field at this location?

2. Based on the definition of the electric field, the electrostatic force that acts on the charge, is the product of the charge and the e-field. Please do the math yourself. Now, since the charge is negative, the direction of the force is opposite to the direction of the e-field.
1. Again, F = Q*E, where F the force vector (in N), Q the charge (scaler, in C) and E the e-field vector (in N/C). You should know that E = F/Q. Please do your math.
