Question

1a. A Gaussian surface is in the shape of a right circular cylinder with each end having a radius of 42.0 cm. The length of the cylinder is 506 cm. Through one end the magnetic fluxis 25.8 milli Weber directed inward. At the other end there is a magnetic field of 75.8 mT, normal to the surface and directed outward. What is the magnetic fux (magnitude and direction) through the curved surface of the cylinder? Give your numerical answer n the form "ab.c x 10A(yy Wb. and give the direction of the nux (mnward" or "outward) as the answer in Question #1b (Hint Recall the Maxwell equation dealing with magnetic nux. The sum of the magnetic flux through all the surfaces must combine to zero. Answer: 1b. 15 the flux inward or outward? Give your answer in the form nwardr or outward

Explanation / Answer

2) Charge Q = C*V

dQ/dt = C*dV/dt

current i = C*dV/dt

Capacitance C = eo*A/d = (8.85*10^-12*3.142*0.0456^2)/(0.0032)

= 1.806*10^-11 C

dV/dt = i/C = (15.5*10^-3)/(1.806*10^-11)

= 8.58*10^8

But dE/dt = (dV/dt)/d = (8.58*10^8)/(0.0032)

= 2.68*10^11 (V/m)/S

(only one question can be answerable at a time. sorry)
