Answer:
0.44m/s
Explanation:
drift velocity=I/nAq 
diameter 12 gauge
wire=0.081inches=0.081*2.5=0.2025cm radius=0.10125cm area=pi*R^2 =20/8.5*10^22*3.14*0.10125^2*10^-4*1.6*10^-19*
V = 0.44m/s
 
        
             
        
        
        
Answer:
The component of F along AB is equal to Fcos45 
F = 520N 
Component along AB = 520cos45
= 367.7N
This is done by rotating the diamonds such that AB is now taken as the x-axis. Then the force F is resolved along AB.
