Answer:
Explanation:
Current, I = 6 A 
diameter of wire, d = 2.05 mm 
number of electrons per unit volume, n = 8.5 x 10^28 
If the diameter is doubled, 
The resistance of the wire is inversely proportional to the square of the diameter of the wire, so the resistance is  one forth an the current is directly proportional to the diameter of the wire so the current is four times the initial value.  
 
        
             
        
        
        
Hahahahaha. Okay. 
So basically , force is equal to mass into acceleration. 
F=ma 
so when F=ma , we get acceleration=6m/s/s 
Force is doubled.
Mass is 1/3 times original.
2F=1/3ma 
Now , we rearrange , and we get 6F=ma 
So , now for 6 times the original force , we get 6 times the initial acceleration.
So new acceleration = 6*6= 36m/s/s 
 
        
             
        
        
        
Lines of Force around an Electromagnet. ... The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.
