Here ,
as the force is proportional to 1/r^2
when the distance is made 0.4 times
new force = 1/0.4^2 times
new force = 6.25 times
the new force is 6.25 times
A) 6.25 times the original force
2. Two ions with charges qc and qo begin at a distance r apart from each...
Two point charges, with charge magnitudes q and Q, are placed a distance r apart. In this arrangement, each point charge experiences a force of magnitude F. In the three scenarios, q. Q, and rare changed to some multiple of their original values. In each case, fill in the missing value on one of the variables that will result in a force between the point charges that is equal in magnitude to the original F. Original Answer Bank Scenario 1...
