Question

A pair of electrically charged objects attract each other with a force of 1 N when they are a distance of 4 m apart. If their charges stay the same, then what will be the attractive force between them when they are 12 m apart? 0.33 N 0.11 N 9.0 N 3.0 N 0.056 N Remember that the electric force F between two charges Q1 and Q2 is given by: F kQ1Q2/r Therefore, the electric force F is INVERSELY proportional to the SQUARE of the distance r between the charges For example, if the distance r is doubled between the charges, then the electric force between them is one fourth (-1/2 * 1/2) its original value. Submit Answer Incorrect. Tries 1/2 Previous TriesC sio A point charge gives rise to an electric field with magnitude 1 N/C at a distance of 3 m. If the distance is increased to 15 m, then what will be the new magnitude of the electric field? 5.0 N/C 0.020 N/C 0.040 N/C 25 N/C 0.20 N/C Remember that the electric field E for a charge Q at distance r is given by: E K/2 Therefore, the electric field E is INVERSELY proportional to the SQUARE of the distance r. For example, if the distance is doubled from the charge, then the electric field is one fourth (-1/2 * 1/2) its original value. Submit Answer Incorrect. Tries 1/2 Previous Tries
