Practice Problem CONCEPTUALIZE Rank these pairs of charged objects in order of increasing magnitude of the attractive force b

Answer 1

Answer #1

Force, F = KQ1Q2/r^2

Force depends on product of charge and inversely on square of distance

1) F = Kx3x2/(2d) ^2 = 1.5K/d^2

2) F = K x 1 x2/(3d)^2 = 2K/9d^2

3) F = K x 2 x 4 /d^2 = 8K/d^2

4) F = K x 4x4 / (2d) ^2 = 4K/d^ 2
