An electron is accelerated by a constant electric field of
magnitude 300 N/C.
(a) Find the acceleration of the electron.
1Your answer was incorrect, but has changed from what was
graded.
Your response differs significantly from the correct answer. Rework
your solution from the beginning and check each step carefully.
m/s2
(b) Use the equations of motion with constant acceleration to find
the electron's speed after 8.00 10-9 s, assuming it starts from
rest.
2 m/s
If two ends of a rope are pulled with forces of equal magnitude
and opposite direction, the tension at the center of the rope must
be zero. True or false?
The answer is false. I chose true though and I'm not
understanding why. Forces act at the center of mass of the object,
so if there are two forces of equal and opposite magnitude, then
they should cancel out resulting in zero tension, no?
1. Magnitude & Direction of Vector
Write a function m-file to find the magnitude and the direction
of cosine of vector F which expresses 3 dimension - x, y, and
z.
Here are requirements for the function m-file.
