Discuss the symmetry between the laws of charles coulomb and sir isaac newton regarding forces

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?

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 c
