The original question is follow. "What is the magnitude of force exerted on charge q1 by charge q2? choices: 1) 0 N 3) 3.77 N 5) 7.63 N 2) 0.108 N 4) 5.39 N 6) 10.8 N The question I am confused about is : "What is the resultant force exerted on...

Corneo if my answer suppose to be negative by force of attractive, than I am confused. The choices that I have doesn't have a negative solution at all. So is my equation set up incorrctly and if so, how should it be set up?

Ok, here is what I have. See attachment to complete the problem. What is the magnitude of force exerted on charge q1 by charge q3 and horizontal component of force exerted? Formula: q1q2 / 4piEor^2 Part 1) (4*10^-6)(2.12*10^-6) / 12.56 (8.85*10^-12)(1*10^-2) = 7.628917917176 N or...

So with number 2 moving to the right should have never been consider because there isn't no left or right only horizontal and vertical. Do I feel like a fool on this one. No further explanation is needed but if you were me, where would you start over at? In order for me to eliminate or...

Doc, here is what I have. This problem seems simple but nerving as well. Here is the question and choices I am given. What you say makes a lot of sense however the choices I have are hard for me to understand. Question: What is the source of the kinetic energy stored in block A? Now I know...

Here is what confusing me. There are choices that states, PE is loss as B is lower, however it is worded in such a way as all the PE loss is transferred to A as Kinetic Energy or only parts of the loss of PE is tranferred to block A as Kinetic energy. As I understand your comments is the...

So in other words, KE is like jump starting the energy in a moving body once it has been jump started, it is only energy until something cause it to stop abruptly of which PE is loss affect and and later transform back to KE. So the answer to my question in as far as the source of the KE in...

To see if I under KE correct, let me give you an example of what i understand. We will use a television for example. Normally when you turn your television off, the power or energy is not there until you turn it on again, however if you have a standby option, would that stand by power be...

Find the tension ( stretching force) on the string whie system is accelerating. I know that the pull on block "A" for acceleration is gm2 / m1 + m2. so what is the source of the kinetic energy store in block "A". :confused:

In my homework assignment, it doesn't mention length. Alicia0

Identical balls are rolled down 2 inclined planes of the same height but different inclines. Do they reach the bottom at the same time. Neglect friction and air resistance. Do the balls have the same speed upon reaching the bottom of the incline? :rolleyes:

There are 2 question but the 2nd question solution is derive from the 1st question. 1. A box is sliding down a plane inclined at an angle of 20 degrees from the horizontal. Find the acceleration of the box, neglecting friction and air resistance. 2. A box that is hurled up the inclined...
