In a single measurement student applied electron gun accelerating voltage of 240 V and measured electron orbital diameter of 8 cm. The applied magnetic induction was the same as in Problem 1. What specific charge of the electron follows from the above measurement

i would think form in reponse to tensional forces

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
