A particle of positive charge Q is fixed at point P. A second particle of mass m and negative charge -q moves at constant speed in a circle of radius r1, centered at P. Derive an expression for the work W that must be done by an external agent on the second particle to increase the radius of the...

Thank you Doc Al for your quick responses i was able to figure out the rest of the problem on my own using the angle. Once again thank you for your help!

It would have to 73.9 because it is positive and i am looking for a positive value

so as Astronuc said it would be x+l not x-l if that is the case the x value would be -2.4 cm or 73.9 cm

it would have to be on the positive side since the charge on q2 is greater that the charge of q2

i placed the charges in a cordinate plane and q2 was to the left of q1 considering it had a coordinate of -2 and to answer your question no it is outside the charges

i assumed it was x-l but i learned that i am wrong by figuring out where the charge will be located

i believe that the charge should be to the left of q1 since q2 has a greater charge than q1 and and sorry the actual calculation was 5.099 cm which is equal to .05099 m

[SOLVED] Coulomb's Law The charges and coordinates of two charged particles held fixed in an xy plane are q1 = +3.5 µC, x1 = 3.0 cm, y1 = 0.50 cm, and q2 = -4.0 µC, x2 = -2.0 cm, y2 = 1.5 cm. At what coordinates should a third charge q3 = +5.5 µC be placed such that the net electrostatic force...

Calculate the amount of energy required to escape from the surface of the following bodies, relative to that required to escape from the surface of Earth.(a) Pluto I keep on getting the same answer to be .011092137 but according to the website i am working on that is not correct. I used the...

Thank you Doc Al for your help

ooo i am in radian mode

Isn't that what i did, i just wrote it in different terms

so i set up the sin 45=o/h and solve so i get hsin 45=0 and i get 2.64e-14 but that is not the correct answer. i do the same thing with cos and get 1.63e-14. where should i go from here

It is moving towards mass 2 and the angle should be 45
