The electric field between two parallel plates has a magnitude of 180 n/c. the two plates are 2.5 cm apart. recall that the magnitude of the charge on an electron is 1.602 × 10-19 c. how much work is done to move an electron from the positive plate to the negative plate?
a. 4.0 × 10-21 j
b. 7.2 × 10-19 j
c. 4.5 j
d. 7200 j
pleasssee !

E = V/d          d = 2.5 cm = 0.025m

180 = V/0.025

V = 180*0.025 = 4.5 V

Work = QV

Work = 1.6 * 10⁻¹⁹ * 4.5 =  7.2 * 10⁻¹⁹ J

Option B.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
