Calculate the gravitational force between two objects when they are 0.630m apart. Each object has a mass of 7.00kg.


Create a class called Account with member variable balance. Create three methods one for Depositing Money, the second for withdrawing money and the third for checking balance. In addition to the three classes, add a constructor to initialize the balance variable. Have the initial balance of the account set to 712,983.88. Have a user deposit any amount and prompt them if they wish to withdraw any amount. If not, print out the balance of the account.
