Question

6/13

2. 2000 N/C uniform electric field points upward. An

electron and a proton are rigidly bound 5.3 x 10^(-11)

meters apart as shown:

Calculate the total force and the total torque on the

object. (Does it matter where you place the axis or origin?)

3. The electric field is the same as problem 4's. This

time, only an electron is in the field. The electron is

half-way between two plates 2.00 cm apart. Which plate

will it hit, and how fast will it hit the plate?

Problem 2)

A) Net force will be Zero

B) Net torque, T = (1.6 x 10^-19 x 2000) x ((5.3 x 10^-11)/2) = 8.48 x 10^-27 Nm
