A particle with a charge of 5nC has a distance of 0.5m away from a charge of 9.5nC. What is its electric potential energy?

Refer to the IS-LM-BP model for an open economy


  1. Draw a diagram that typically illustrates the IS-LM-BP model, with the slope of the BP curve flatter than that of the LM curve. Label the axes properly and reflect equilibrium.
  2. How was the LM curve derived and defined, what does the slope of the curve depend on and what changes in what variables will shift the curve to the right?
  3. How was the I|S curve derived and defined, what does the slope of the curve depend on and what changes in what variables will shift to the curve?
  4. What does the BP curve reflect and what do points on, below and above the BP curve indicate?

Create a program that will compute the simple interest loans in the bank. The program will ask the user to input the principal amount , the rate per annum and the time (in years).




Given the formula:




Interest = Principal Amount * RateperAnnum * Time / 100



  1. Print out all numbers from 1 to 100 that is divisible by 3 using a for loop just like the last problem, but this time, with each number only separated by the space like that of the sample output.
