A large electroscope is made with "leaves" that are 78-cm-long wires with tiny 50g spheres at the ends. When charged, almost all the charge resides on the spheres.

No title provided

1. If the wires each make a 26 angle with the vertical (Figure 1) , what total charge Q should have been applied to the electroscope? Ignore the mass of the wires.

61. An electron with a speed of 7.30 x 10 8 cm/s enters an electric field of magnitude 1.28*10 3 N/C, traveling along the field in the direction that retards its motion.

a) How far will the electron travel in the field before stopping momentarily and

_____m

b) How much time will have elapsed?

_____s
