When I used a=F/m I got (4.3E-16)/9.11E-31) which equals 4.72E14
when I try a=0 in the horzizontal displacement formula, I got t= .000002
Do I use that in the vertical diplacement formula for t and then 4.72E14 for a?
Homework Statement
An electron with a speed of 1.9 × 107 m/s moves horizontally into a region where a constant vertical force of 4.3 × 10-16 N acts on it. The mass of the electron is 9.11 × 10-31 kg. Determine the vertical distance the electron is deflected during the time it has moved 34 mm...
That did it!
I came up with 424pi/3
When I initially tried the shell method I was using just x for the radius instead of 7-x. Thanks again for the help!
since its rotating about the line x=7, I solved for y first
Im using pi*intergral from 0 to 16 of ((7-sqrt(y))^2-(7-5)^2)dy
I think I'm messing up with what my inner and outer radius' are and possibly the bounds
I'm have trouble with a homework problem having to do with find volume of an area. the problem reads:
Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line.
y=x^2 , y=0 , x=2 , x=4;
about the line x=7
I've tried using the washer...
