Explanation / Answer
1) for Tension to be zero I*L*B = m*g
==> I*B = m*g/L
==> I = (m/L)*g/B
==> I = 0.06*9.8/4 = 0.147 A
2)E = change in flux /change in time
change in flux = (B*A2 -B*A1)
A1 = 0
A2 = 0.5*0.6*6*0.6*6*tan(19)
so E = 0.6*0.5*0.6*6*0.6*6*tan(19)/6 =0.223 V
3)a)tan(theta1) = (3-2.1)*10^2 /90 = 90/90 = 1
==> theta 1 = 45 degree
b)sin theta1/sin theta2 = 1/1.33
==> sin theta2 = 1.33*sin(45 degree)
==> theta 2 = arcsin(1.33*sin(45 degree)) = 70.13 degree
c) phi = 90-70.13 = 19.87 degree
d)h/2.1*10^2 = tan(phi)
==> h = 210*tan(19.87 degree) = 75.89 m
4)a) sin (theta c) = 1/4/3
==> theta c = arcsin(3/4) = 48.59 degree
b)sin(theta)/sin(30) = 1/4/3
==> sin theta = 3*sin(30)/4
==> theta = arcsin(3/8) = 22.02 degee
c)h+xtan(30) = x+htan(22.02)
==> h(1-tan(22.02) = x(1-tan(30))
==> x = h(1-tan(22.02)/(1-tan(30)) = 0.043*h
now
0.043*4+h = 1
==> h = 1/1.043 = 0.9587 m
5) q*v*B = m*v^2/r
==> q*B = m*v/r
==> qB = m/T
==> T = m/qB
==> f = 1/T = qB/m = 1.6*10^-19*5*10^-5/(9.1*10^-31) = 8.79*10^6 Hz or 8.79 MHz
6)a) v = sqrt(2*q*V/m) = sqrt( 2*1.6*10^-19*2100/(1.67*10^-26)) = 2.01*10^5 m/s
b)r = mv/qB = (1.67*10^-26*2.01*10^5)/(1.6*10^-19*0.8) = 0.026 m or 2.6 cm
7)t = IAXB = IABin(theta) = 0.49*25*10^-4*0.8*sin(30 degree)=0.00049 N-m
