Three point charges are located at the following positions: Q1 =2.00 microC at x = 1.00 m; Q2 = 3.00 microC at x = 0; Q3 = -5.00microC at x = -1.00 m. What is the magnitude of the force on the3.00-microC charge?

Two point charges, separated by 1.5 cm, have charge values of 2.0and -4.0 microC, respectively. What is the magnitude of theelectric force between them?

Two point charges of +3.0 microC and -7.0 microC are placed at x =0 and x = 0.20 m. What is the magnitude of the electric field atthe point midway between them?

two point charges, q1=-2 microC and q2= -2microC are located onthe y axis. The charge at q1 is located at y=+1m and charge q2 aty=-1m.

1. Determine the electric field at point P on the x-axis atx=0.5m. specify direction

2. calculated the electric force on a point charge particle withq3=3 microC placed at P. specify direction

3. if you place q3 in item (b) at the origin of the coordinatesystem O and release it, the charge remains at that position, forthe net force on it is zero. You now displace q3 by a smalldistance along the x-axis and release it again. does charge q3: (i)remain at the new position (ii) move further away from origin (iii)return to origin. justify your answer

4. a student replaces charge q'2 by a unknown charge q2. placingnow charge q3=3microC at y=0.5 on the y axis, he notes that q3remains at rest. find the value of q'2

Three charges, q1 = 7.78nC, q2 = -5.45nC and q3 = 3.26nC are at thecorners of an equilateral triangle, as shown in the figurebelow.

The angle is 60.0o and L = 0.478 m. We are interested in the pointmidway between the charges q1 and q2 on the x axis.
For starters, calculate the magnitude of the electric field dueonly to charge q3 at this point.

Now calculate the magnitude of the electric field from all threecharges at a point midway between the two charges on the xaxis.

Calculate the angle of the electric field relative to the positive(to the right) x-axis, with positive values up (Counter-Clock Wise)and negative down (Clockwise). (enter the answer with units ofdeg)

If a tiny particle with a charge q = 1.06nC were placed at thispoint midway between q1 and q2, what is the magnitude of the forceit would feel?

Coulomb's law for the magnitude of the force between two particleswith charges and separated by a distance is |F| = K |QQ'|/d^2 whereK = 1/4piEo, Eo = 8.854 x 10^-12 C^2/Nxm^2. is the permittivity offree space.

Consider two point charges located on the x axis: one charge, q1 =-11.5nC , is located at x1 = -1.715 m; the second charge, q2 =34.5nC , is at the origin x = 0.00000.

What is the net force exerted by these two charges on a thirdcharge q3 = 49.5nC placed between q1 and q2 at x3 = -1.240m ?

Your answer may be positive or negative, depending on the directionof the force.
