Question

PROBLEM 1 An electron (of mass me), at rest, is located at one end of a long TV picture tube of length L. It experiences a constant horizontal force from the TV tube as it travels through the TV tube. The electron reaches the opposite end of the TV tube after a time of t. Ignore air resistance. (a) Determine the electron's acceleration during it's "journey". Express your answer in terms of the following variables: me, L, t, and/or g. (b) Determine the magnitude of the net force acting on the electron. Express your answer in terms of the following variables: me. L, t, and/or g

Explanation / Answer

a.

Using 2nd equation of motion

L = 0.5*a*t^2

a= (2*L/t^2)

--------

B. Force,

F=ma

= 2mL/t^2

----

C.

Acceleration a= 2*0.12/0.12^2= 16.67 m/s/s

Force, F= 9.11*10^-31*16.67= 1.518*10^-29 N

Comment in case any doubt . Goodluck
