- Show the calculations and a clearly labelled diagram to determine what will happen to each of the droplets described in questions 5-7 (accel up, down or freeze mid-air). 5. A 1.88times 10^-16 g droplet has gained 45 electrons and is released in a 375N/C[D] electric field. 6. A 2.525times 10^-15 xg droplet has lost 216 electrons and is released in a 715.3N/C[U] electric field. 7. A 7.13times 10^-15 g droplet has lost 173 electrons and is released in an electric field that has a strength of 1686N/C [U].
