Algebra.Com's Answer #693274 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The force of attraction between two magnets is inversely proportional to the square of the distance between them. When the magnets are r cm apart, the force of attraction between them is F newtons(N). If the distance between the magnets is increased by 400%, the force of attraction between them becomes cF N. Find the value of c. \n" ); document.write( "----------- \n" ); document.write( "An increase of 400% --> 5 times the distance. \n" ); document.write( "--> 1/25 the force. \n" ); document.write( "c = 1/25 \n" ); document.write( " \n" ); document.write( " |
