Homework Statement
The electric potential of a region of space is V= 200 / sq root (x^2 + y^2), where x and y are in meters. What are the strength and direction of the electric field at (x,y) = (2m,1m)?

I took the negative derivative of V to find what...
when we triple the net force, A = F / m there will be a value of 3 next to the F. it looks like this A = 3F / M (if F increased by 3x and m stayed the same A would increase by a factor of 3 also)
this relation proves that the acceleration does increase by 3x. so 18 seems like the answer
For (a) would it be .1313 divided by Avogadros number?
what about for part (b) i use the law of conservation which is Kf + qVf = Ki + qVi or Kf = Ki - qΔV and it starts from rest so Ki is 0,
essentially 1/2mv^2 = -qΔV
solve for v to find final speed
the problem is i don't know what the charge...
Well the atomic mass of Xenon is 131.293 g/mol, so in kg it would be .1313kg/mol would it not?
Also for part b i have been trying to use the Kf + qVf = Ki + qVi (conservation of energy) but I do not know the value of the charge. So I'm thinking there might be an equation I am missing or...
My name is Devon, I'm a sophomore at East Stroudsburg University. I am majoring in Engineering and I have been pounded with tough physics problems since freshman year. I enjoy physics and like learning it. It is great to be a part of a forum that focuses on my main subject. This forum seems...
Homework Statement
Been stuck on this problem. Any help will be greatly appreciated
1. The (actual) spacecraft Deep Space 1 tested an ion drive engine in which Xenon atoms
were accelerated (maximum voltage of 1,300 volts), neutralized and used to provide
thrust. The probe carried 74 kg of...
