2.(10pts) A small microbe of mass m = 5.01 10'\"5 kg is in equilibrium between two parallel plates which have a constant electric eld between them of value E = 1534 N/C (V [m] downward, as shown. Find the excess negative charge, Q, and the number of (excess) electrons on the microbe? (Hint: Let the force of gravity be mg acting downward. Round the number of excess charges to the nearest integer.) Considering that the microbe has an enormous number of atoms, what does your result show about the strength of the electric and gravitational forces? immwr-v-Hn-mm-eeu-r- and +
