GEO 106 : Territory and Territoriality

FN +mg +fk +F=0

FN is the normal force,mg is mass and gravitational acceleration which equals toweight, and F is force. Sowhat is fk? Blah I can't believe I don't know this.

(part 1 of 3)
A rectangular loop of copper wire of re-
sistance R has width a and length b. The
loop is stationary in a constant, uniform mag-
netic field B0, directed into the page as shown
above.

(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

(part 3 of 3)

What is the net magnetic force on the loop of wire?

1.F = 70 N

2.F = 12 N

3.F = 0 N

4.F = 14 N

5.F = 40 N

6.F = 22.2222 N
