Question
STEP 1: Create the Multifile Project and the Main (Base) Class
Create a new project that consists of the base class BankAccount.
The BankAccount class should contain, at minimum, the following members.
STEP 2: Create the CheckingAccount Class Derived From the BankAccount Class
The class CheckingAccount should contain, at a minimum, the following members.
STEP 3: Create the SavingsingAccount Class Derived From the BankAccount Class
The class CheckingAccount should contain, at a minimum, the following members.
STEP 4: Test Program Operation
STEP 1: Create the Multifile Project and the Main (Base) Class
Three charges are fixed to an x, y coordinate system, at distances dx=3 m and dy=4 m as shown in the figure, where ?=53.1 degree. The charges are q1 = 18 ?C, q2 = -12 ?C, and q3 = 45 ?C. Determine the magnitude of the electrostatic force F13 on q3 due to q1 What is the y component of F13? Find the magnitude of the force F23 on charge q3 due to charge q2 Determine the x component of the net electrostatic force Fx on q3 Determine the magnitude the net electrostatic force F on q3Explanation / Answer
