F = k q1q2/ r^2
2.6 = 9*10^9*3.6**10^-6* q2 / 0.3^2
q2 = 7.22 *10^-6 C
since the charges attracts each other so it must be negative.
======
F = k q^2 / r^2
F = k ( ne) ^2 / r^2
F = k n^2 e^2 / r^2
4.55*10^-21 = 9*10^9* n^2 * ( 1.6*10^-19)^2 / ( 5.4*10^-3)^2
n = 24

A. Find the magnitude and sign of q1 & q2. Constants Part A Two point charges gi and q are held 4.00 cm apart. An electron released at a point that is equidistant from both Find the magnitude and sign of qi and q2 charges (see the figure (Figure 1)) undergoes an initial acceleration of 8.10x1018 m/s2 directly upward in the figure, parallel to the line connecting q and q Figure < 10, 1 》 Submit Request Answer 41 ▼...
5) A 6.0 kg object is experiencing 2 forces with identical magnitude of 10.0 N. What is the maximum and minimum magnitude of the acceleration that the object can experience based on the possible directions that the forces may act upon the object?
You own n colors, and want to use them to color 6 objects. For each object, you randomly choose one of the colors. How large does n have to be so that odds are that no two objects will have the same color (i.e., every object is colored in a different color)?
Q1-1An object has a net force F → = (14.9x ^ +8.19y ^ ) N exerted on it. What is the magnitude of the acceleration (in unit of m s 2) if the object has a mass of 5.46 kg? Q2-An object has a net force F → = (24.2x ^ +21.1y ^ ) N exerted on it. What is the magnitude of the force (in unit of newton)?
As shown in the figure below, seven forces all with magnitude |F| = 57 N are applied to an irregularly shaped object. Each force is applied at a different location on the object, indicated by the tail of the arrow; the directions of the forces differ. The distances shown in the diagram have these values: w=7m, h=16 m, and d=12 m.For each force, calculate the z component of the torque due to that force, relative to location A (x to...

Two Charges of the same magnitude q1 = q2 = 10^-6 C are located at a distance r. it takes 1J of energy to move q2 away to a distance r'>>>r, connsider r' as infinity. a) what is the sign of the charge q2 if the charge q1 is postiive? b) what is the distance r? c) what is Vr->r'=Vr' - Vr? please explain the steps to get each anwser
Charge q1 is placed a distance r0 from charge q2 . What happens to the magnitude of the force on q1 due to q2 if the distance between them is reduced to r0/4 ? What is the electrostatic force between and electron and a proton separated by 0.1 mm?

Three forces act on a moving object. One force has a magnitude of 78.6 N and is directed due north. Another has a magnitude of 55.3 N and is directed due west. What must be (a) the magnitude and (b) the direction of the third force, such that the object continues to move with a constant velocity? Express your answer as a positive angle south of east.
