Vectors A and B lie in the xy-plane. Vector A has a magnitude of 19.1 and is at an angle of 125.5º counterclockwise from the +x-

axis. Vector B has a magnitude of 27.7 and is 235.3° from the +x-axis. Resolve A and B into components, and express using ijk unit vectors, A = Azi + Ayj + Azk B = Bzi + Byj + Bzk where Ax, Ay, A, and Bx, By, and B, are the calculated values of the x-, y-, and z-components of vectors A and B, respectively.

Three point charges lie in a straight line along the y-axis. a charge of q1 = -9.10 µc is at y = 6.30 m, and a charge of q2 = -7
inysia [295]

Answer:

 Electric field E = kQ/r^2  

Distance between charges = 6.30 - (-4.40) = 10.70m  

Say the neutral point, P, is a distance d from q1. This means it is a distance (10.70 - d) from q2.  

Field from q1 at P = k(-9.50x^10^-6) / d^2  

Field from q2 at P = k(-8.40x^10^-6) / (10.70-d)^2  

These fields are in opposite directions and are equal magnitudes if the resultant field = 0  

k(-9.50x^10^-6) / d^2 = k(-8.40x^10^-6) / (10.70-d)^2  

9.50 / d^2 =8.40 / (10.70-d)^2  

d^2 / (10.70-d)^2 = 9.50/8.40 = 1.131  

d/(10.70-d) = sqrt(1.1331) = 1.063  

d = 1.063 ((10.70-d)  

= 10.63 - 1.063d  

2.063d = 10.63  

d = 5.15m  

The y coordinate where field is zero is 6.30 - 5.15 = 1.15m

Nina [5.8K]

Answer:

4306.8625 J or 344549/80J (fraction form)

Explanation:

kinetic energy= \frac{1}{2\\}mv²

= \frac{1}{2}×72.5×10.9²

= 4306.8625 J  or 344549/80 J
