Which of the following best represents the resultant electrostatic force on qA due to the other charges? (The formula for electrostatic force is  where q is a test charge, Q is the source charge, and r is the distance between their center of masses.)
  • a)
  • b)
  • c)
  • d)
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Which of the following best represents the resultant electrostatic for...
Given this formula, we have to extrapolate that charge q is directly proportional to F,  while r has an inverse-square relationship to F.

Each charge will exert a force on charge A, and their force vectors are in the diagram below:
If the force of charges B and D on charge A are each 1 unit, then the force of charge C will be 1/2 unit. The doubling of the charge on C is balanced by the doubling of the distance, but distance is squared, so the ratio becomes

The resultant vector would be the following:
