Homework Statement Particles 2 and 4, of charge -e, are fixed in place on the y-axis at y2=-10.00 cm and y4=5.00cm. Particles 1 and 3, of charge -e, can be moved along the x axis. Particle 5 of charge +e is fixed at the origin. Initially particle 1 is at x1= -10.0cm and particle 3 is at x3=...

The first step when doing vector addition or subtraction is to find the component form of each vector. Components are related to x and y coordinates and are found using A_x=\vecA cos\Theta and A_y=\vecA sin\Theta . Once in component form you add A_x+B_x and A_y+B_y, this gives you components for...

It took me a while and i feel like a dunce...the assumption is that 1 day = 1 day...once i saw that the rest was easy thanks for pointing me in the right direction.

Thanks. that helps a bit. I got the part (a). And yes we're using the Halliday book. And yes he does tend to rant...

I am a first year University Physics student and a longgg time out of high school. I am strong in math, but I am feeling very shaky about this physics course. our first homework assignment had a couple of problems that I found a little confusing. Here is trhe first one: For about ten years...
