Answer:
Explanation:
for the unit vector, we need to divide the given vector by its norm, because it should be in the SAME direction as the original vector, but of magnitude "1".
We notice that the norm of the given vector is:
Then, the unit vector becomes:
Answer:
Electric field, E = 40608.75 N/C
Explanation:
It is given that,
Mass of electrons,
Initial speed of electron, u = 0
Final speed of electrons,
Distance traveled, s = 6.3 cm = 0.063 m
Firstly, we will find the acceleration of the electron using third equation of motion as :
Now we will find the electric field required in the tube as :
E = 40608.75 N/C
So, the electric field required in the tube is 40608.75 N/C. Hence, this is the required solution.
