Question

(a) Two point charges totaling 7.00

Answer #1

**q1q2 = Fr^2/K**

**q1q2 = 0.3 * 0.441*0.441/(9e9)**

**q1q2 = 6.48 *10^-12**

**use thw identity (q1-q2)^2 = (q1+q2)^2
-4q1q2**

**(q1-q2)^2 = 7e-6*7e-6 -(4*6.48 e-12)**

**q1-q2)^2 = 23.08 *10^-12**

**(q1-q2) = 4.8 uC**

**as (q1+q2) = 7 uC**

**adding them**

**2q1 = 11.804**

**q1 = 5.9 uC or 6 uC (largest
charge)**

**q2 = 7-5.9 = 1.1 uC or 1uC ( smallest
charge)**

**b.**

**when force is attractive,**

**(q1-q2)^2 = 7e-6*7e-6 -(4*-6.48
e-12)**

**q1-q2 = sqrt(74.92 e-12)**

**q1 -q2 = 8.655 uC**

**q1+q2 = 7uC**

**adding them**

**2q1 = 15.655**

**q1 = 7.82 uC ( largest charge)**

**q2 = 0.82 uC (smallest charge)**

Positive point charges q = 7.00 μC and q′= 2.00 μC are moving
relative to an observer at point P, as shown in the figure (Figure
1). The distance d is 0.130 m , v = 4.60×106 m/s , and v′= 9.20×106
m/s . When the two charges are at the locations shown in the
figure, what is the magnitude of the net magnetic field they
produce at point P? What is the direction of the net magnetic field
at...

three point charges lie along a circle of radius r= 3.00 cm:
q1=7.00 nC at angle 30, q2 = +9.00 nC angle 180 , and q3 = +7.00 nC
at angle 330 shown in the figure . find the magnitude E of the
electric field created by the three charges at the center O of the
circle :
A. E= 8.00 =10 NUC
B.E= 1.14 = 10 NUC
C. E=2.00= 10 NUC
D.E= 1.60 = 10 NUC
