the repulsive force between the north poles of 2 magnets is inversely proportional to the square of the distance between the 2 poles.
\n" ); document.write( "-----
\n" ); document.write( "f = k/d^2
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"k\" using \"if the repulsive force is 40 pounds when the distance between the 2 poles is 2 inches\"
\n" ); document.write( "40 = k/2^2
\n" ); document.write( "k = 160
\n" ); document.write( "-----
\n" ); document.write( "f = 160/d^2
\n" ); document.write( "------
\n" ); document.write( "What is the repulsive force when the distance between the 2 poles is 4 inches?
\n" ); document.write( "--
\n" ); document.write( "f(4) = 160/4^2
\n" ); document.write( "f(4) = 10 pounds
