Consider aman standing on a scale which is
placed in anelevator. When the elevator is
stationary,the scale reading is Ss .
blocks frommoving?
Find Sup ,the scale reading when the el-
evator ismoving upward with acceleration
?a = 1 /gËj, in terms of S.
1. S up = 7/5 Ss
2. S up = 5/4 Ss
3. S up = 3/2 Ss
4. S up = 0ms2
5. S up = 3 /5 Ss
6. S up = 2 /3 Ss
7. S up = 7 /6 Ss
8. S up = 5/6 Ss
9. S up = 6 /5 Ss
10. S up = 4/5 Ss

(part 1 of 3)A rectangular loop of copper wire of re-sistance R has width a and length b. Theloop is stationary in a constant, uniform mag-netic field B0, directed into the page as shownabove.
(part 2 of 3) Let :
n = 9 , a= 9 m, b= 7 m, and B0 = 2 T.
1.E = 120 V
2.E = 1134 V
3.E = 2268 V
4.E = 240 V
5.E = 1440 V
6.E = 0 V
