4. Four point charges are placed as shown below. Find the net field at the test point P, located a distance yabove the middle of the sources, for each of the following sets of parameters. The distance d betweenadjacent sources is d=1.0 x 10-4 m.You may and even are encouraged to reuse any calculations that are needed more than once, symmetryarguments, and appropriate approximations as long as you make it clear what you are doing. Yourcalculations need to give numbers that would be good to 2 significant figures.*Pya) Q₁ +2.0 nC; Q2 +2.0 nC; Q3=-2.0 nC; Q4--2.0 nC; y=4.0 × 10-4 mb) _Q₁=+2.0 nC; Q2=+2.0 nC; Q3=-2.0 nC; Q4=-2.0 nC; y=4.0 × 10-² mc) Q₁=+2.0 nC; Q2=+2.0 nC; Q3=+2.0 nC; Q4=-2.0 nC; y=4.0 × 10-² m

Responses should be as simple as possible, and in typed form, with all applicable units, following a clear and straightforward logical structure. NO hand-drawn explanations are allowed. Ensure the appropriate use of significant figures, and when applicable, employ the "variable space" framework for providing answers.

Please help me with the following and make sure its correct 100%, explain, thanks Q: A charge of -2.65 nCnC is placed at the origin of an xy��-coordinate system, and a charge of 1.90 nCnC is placed on the y� axis at y� = 4.20 cmcm . part A. If a third charge, of 5.00 nCnC , is now placed at the point x� = 3.15 cmcm , y� = 4.20 cmcm find the x� and y� components of the total force exerted on this charge by the other two charges. Enter your answers in newtons separated by a comma. Part B. Find the magnitude of this force. Express your answer in newtons. Part C. Find the direction of this force. Express your answer in degrees.

Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures. You may work together, but make sure that you are working--not just watching. The magnitude of the force of attraction between the proton and electron in a hydrogen atom is: F = where e is the magnitude of the charge, k is a constant, and r is the radius of the circular orbit. Assume the proton is fixed in place and the electron is in a circular orbit of radius ri. The electron then "jumps" to a new, smaller radius r2. What is the change in the total mechanical energy of the system (in terms ri, r2, e, and k)? Hint: Use dynamics to calculate the kinetic energy for the electron in the initial and final orbits, then calculate the potential energy in both orbits (you will need to develop an expression for the potential energy and remember the force is attractive). Do you know what form the change in mechanical energy takes?

1. Consider the four point charges shown in the figure on the right, arranged on the edges of a square of side a. a) Find the value of Q (in terms of g), such that the electric field at the center of the square points down (i.e., it only has a -y component). Show all work and justify any assumptions you -29 a a/2 make. b) Assuming Q has the value found in part (a), find the force exerted by the four corner charges on a fifth charge -q placed at the center of the square. c) Also using the result from (a), find the electric field at point P (shown in the figure) created by the four corner charges (there is no charge at the center of the square for this part).
