Can any body help me with the solutions of one or more of these questions which are in the Book "University Physics 10th edition" chapter 28, questions: 1,4,9,13,29,57,58 Pleeeeeease(adsbygoogle = window.adsbygoogle || []).push({});

q1) A particle with a charge of -1.24 x 10(-8) C, is moving with instantaneous velocity v=(4.19x10(4) m/s)i + (-3.85x10(4) m/s)j.

What's the force exerted on this particle by a magnetic field

a) B = (1.40 T)i

b) B = (1.40 T)k?

-------------------------------------------

q4) A particle with a mass of 1.81x10(-3) kg and a charge of 1.22 x 10(-8) C has at a given instant a velocity v=(3.11 x 10(4) m/s)j. What are the magnitude and direction of the particle's acceleration produced by a uniform magnetic field B= (1.63 T)i + (0.980 T)j?

-------------------------------------------

q9)A circluar area with a radius of 6.50 cm lies in the xy-plane. What's the magnitude of the magnetic flux through this circle cue to a uniform magnetic field B = 0.230 T

a) in the +z direction?

b) at an angel of 53.1 from the +z-direction?

c)in the +y-direction?

--------------------------------------------

q13) An electron at point A in figure 38-39 has a speed v0 of 1.41 x 10(6) m/s. Find:

a) the magnitude and direction of the magnetic field that will cause the electron to follow the semicircular path from A to B;

b) the time requied for the electron to move from A to B.

q29) A wire along the x-axis carries a current of 3.50 A in the naegative direction. Calculate the force (expressed in terms of unit vectors) on a 1.00 cm section of the wire exerted by these magnetic fields:

a) B= -(0.65 T)j;

b) B= +(0.56 T)k;

c)B= -(0.31 T)i;

d)B= +(0.33 T)i - (0.28 T)k;

e) B= +(0.74 T)j - (0.36 T)k.

and also who has the same book can help me with questions 57 and 58

I hope to answer these questions today or tomorrow! :(
