QUESTION 2 When placed 5 cm away from an unknown charge Q, a 0.5 x 10° C charge experiences a repulsive electric force of magnitude 11.2 N. Calculate the magnitude of the charge on Q. (Give your answer in coulombs but don't include the units.) QUESTION 3 -e +e -е 8 cm 2 cm Two electrons (-e) are separated by 10 cm, and a proton (+e) is placed on the line connecting the two such that is is 2 cm from one of the electrons (see diagram). Calculate the magnitude of the net electric force on the proton. (Give your answer in newtons but don't include the units.) QUESTION 4 Two electrons and one proton are placed on the corners of a square, such that the proton is opposite the empty corner. Which of the following statements is correct? O The net electric field at the empty corner is directed away from the center of the square. O The net electric field at the empty corner is directed toward the center of the square.

Three charges are located as shown. Find the total force on q3 due to qi and q2. Make a careful drawing on the figure that shows each force vector and its 2 = +50µC components. 93 = +40µC +) P. q1 -25 µC 1 meter Calculate the electric field at the point P (where q3 currently is). Calculate the electric force that q3 exerts on q2. Draw the force vector on the figure and label it F32.

A point charge ?1 with a charge 2.0 X 10−6 C is initially at rest at a distance of 0.25 m from second charge ?2 with a charge 8.0 X 10−6 C and mass 4.0 X 10−9 kg. Both charges are positive. Charge ?1 remains fixed at the origin, whereas ?2 travels to the right upon release. a) Determine the speed of charge ?2 when it reaches a distance of 0.50 m from ?1 Diagram posted below.

I need help with this physics question

m2 Two point charges (Q₁ = 2.1 µg) begin at rest a distance xo +01 = = 4.2 nC with mass mi 1.6 µg, and Q₂ 6.4 nC with mass 1.7 cm apart. Both are free to move. +Q₂ Xo = = Calculate the velocity of each charge at the moment charge Q2 has moved 1.0 cm.

Two equally charged, 1.00 g spheres are placed with 4.00 cm between their centers. 2 When released, each begins to accelerate at 225 m/s . As the spheres move, do you expect the force between them to increase, decrease or remain the same? Use an equation to justify your reasoning. Calculate the spacing needed between the spheres that would cut the force between them in half.

Part A The three point charges +4.0 µC, -5.0 µC, and -9.0 µC are placed on the x-axis at the points x = 0 cm, x = 40 cm, and x = 120 cm, respectively. What is the x component of the electrostatic force on the -9.0 µC charge due to the other two charges? (k = 1/4TTE0 = 9.0 × 10° N • m2/c2) 0.64 N -0.55 N -0.41 N 0.55 N 0.41 N Submit Request Answer

Referring to (Figure 1), suppose q2q2 is not known. Instead, it is given that q1+q2q1+q2 = -2.3 μCμC. Assume that the number of field lines shown precisely represents the ratio of the magnitudes of the charges. Find q1, q2, and q3.

An average human weighs about 700 N .If two such generic humans each carried 3.0 C coulomb of excess charge, one positive and one negative, how far apart would they have to be for the electric attraction between them to equal their 700 N weight?   So first I AM BLIND! YOUR IMAGES/EQUATION EDITOR CAN'T BE READ BY MY SCREEN READER!! SO FOR HELP PLEASE JUST WRITE IT OUT IN HTML TEXT (THE LITERL CHARACTERS YOU ARE READING RIGHT NOW) PLEASE!! So I know f=1/(4pi*epsilon)*abs(q1*q2))/r^(2)        and we are looking for R here. o first epsilon = 9.8*10^(9) and with all of that information you need to manipulate to solve for R. I get r= sqrt(1/4*pi()*epilison)*abs(q1*q2). From there I am getting a wrong answer and can't figure out what is going on with thealgebra. So could someone help me figur out what needs to be done to the initial equation to solve for r? and finally again please no graphs, images, or anything and  just  can read the html text. appreciate the help if someone  is willing to…
