Electric potential ( with angle)
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)? Homework EquationsThe Attempt at a Solution I took the negative derivative of V to find what...- dmack15

What Happens to Acceleration If Net Force Triples?
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- dmack15

Electrical potential involving a spacecraft
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...- dmack15

Electrical potential involving a spacecraft
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...- dmack15

Hello my fellow physics friends
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...- dmack15

Electrical potential involving a spacecraft
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...- dmack15
