Answer:
The decision designer is a step-wise process
Explanation:
A typical decision tree will be like this: 
Are there any forces? 
YES - then calculate the resultant forces              NO - Then no calculations are needed
IF YES - Are the forces balanced?                         NO - Then no calculations
IF YES - Then calculations can be done. 
Resolve the forces to find the resultant of the forces in the question. 
 
        
             
        
        
        
Answer:
a) the charge of an electron is equivalent to the magnitude of the elementary charge but barring a negative sign since the side of the elementary charge is roughly 1.602 * 10 - 19 Columbus then the charge of the electronic is-1.602 * 10 - 19
b) b=2T on the electron moving in the magnetic field
