I don't know from what dusty corner of my brain I pulled that equation for acceleration. Ugh... silly kinematics.
Vorcil, the issue with that, is that I'm to show all work, and there is no calculus in this classical course. If I work out the derivative on the homework, my professor would be...
Homework Statement
An electron starts from one plate of a charged closely spaced (vertical) parallel plate arrangement with a velocity of 1.63x104 m/s to the right. Its speed on reaching the other plate, 2.10 cm away, is 4.15x104 m/s.
...
If the plates are square with an edge length of 25.4...
I must be daft!
And I made a typo, it's 0.09 and not 0.90. But that's beyond the point!
The distance from one corner of an equilateral triangle is equal to a hypotenuse made from a right triangle with one leg half the length of teh sides of the triangle and the other leg equal to 1/3 the...
Homework Statement
Given an equilateral triangle with sides 20-cm, with point charges at each point:
q1 at the top with a charge of +4.0uM,
q2 at the bottom right with a charge of -4.0uM, and
q3 at the bottom left with a charge of +4.0uM.
k is assumed to be exactly 9.00x109 N-m2/c2...
