Question
A positive charge Q is on the y-axis at a distance a from the origin, and another positive charge q is on the x-axis at a distance b from the origin.(a) For what value(s) of b is the x-component of the force on q a minimum? (Use any variable or symbol stated above as necessary. Enter your answers from smallest to largest starting with the first answer blank. Enter NONE in any remaining answer blanks.)
b1 = ..........

Explanation / Answer
force on the charges is given by F = kq1q2/r^2 so to have large force distance must as low as poss and magnitude of charges must as high as possible and vice versa
