problem set 9 error

Guest Status: Reputation: 1

dudes,

i think there is a mistake in the problem set #9 solution. okay, look at question 2, it says the cross sectional area is 1 cm sq. now read the solution, second line (Ans. 2). where it says

R(c) = L / (mu) S

there S should be 1 X 10^-4 m sq, right?

instead it says 2 X 10^-4 m sq.

also on the last line of 2 a)'s solution where the B = flux / area, area is again taken as 2 cm sq?

why so? can u explain or is it plain wrong?

thanx buds
